15 Common Problem-Solving Interview Questions

In an interview for a big tech company, I was asked if I’d ever resolved a fight — and the exact way I went about handling it. I felt blindsided, and I stammered my way through an excuse of an answer.

It’s a familiar scenario to fellow technical job seekers — and one that risks leaving a sour taste in our mouths. As candidate experience becomes an increasingly critical component of the hiring process, recruiters need to ensure the problem-solving interview questions they prepare don’t dissuade talent in the first place. 

Interview questions designed to gauge a candidate’s problem-solving skills are more often than not challenging and vague. Assessing a multifaceted skill like problem solving is tricky — a good problem solver owns the full solution and result, researches well, solves creatively and takes action proactively. 

It’s hard to establish an effective way to measure such a skill. But it’s not impossible.

We recommend taking an informed and prepared approach to testing candidates’ problem-solving skills . With that in mind, here’s a list of a few common problem-solving interview questions, the science behind them — and how you can go about administering your own problem-solving questions with the unique challenges of your organization in mind.

Key Takeaways for Effective Problem-Solving Interview Questions

• Problem solving lies at the heart of programming. 
• Testing a candidate’s problem-solving skills goes beyond the IDE. Problem-solving interview questions should test both technical skills and soft skills.
• STAR, SOAR and PREP are methods a candidate can use to answer some non-technical problem-solving interview questions.
• Generic problem-solving interview questions go a long way in gauging a candidate’s fit. But you can go one step further by customizing them according to your company’s service, product, vision, and culture. 

Technical Problem-Solving Interview Question Examples

Evaluating a candidates’ problem-solving skills while using coding challenges might seem intimidating. The secret is that coding challenges test many things at the same time — like the candidate’s knowledge of data structures and algorithms, clean code practices, and proficiency in specific programming languages, to name a few examples.

Problem solving itself might at first seem like it’s taking a back seat. But technical problem solving lies at the heart of programming, and most coding questions are designed to test a candidate’s problem-solving abilities.

Here are a few examples of technical problem-solving questions:

1. Mini-Max Sum  

This well-known challenge, which asks the interviewee to find the maximum and minimum sum among an array of given numbers, is based on a basic but important programming concept called sorting, as well as integer overflow. It tests the candidate’s observational skills, and the answer should elicit a logical, ad-hoc solution.

2. Organizing Containers of Balls  

This problem tests the candidate’s knowledge of a variety of programming concepts, like 2D arrays, sorting and iteration. Organizing colored balls in containers based on various conditions is a common question asked in competitive examinations and job interviews, because it’s an effective way to test multiple facets of a candidate’s problem-solving skills.

3. Build a Palindrome

This is a tough problem to crack, and the candidate’s knowledge of concepts like strings and dynamic programming plays a significant role in solving this challenge. This problem-solving example tests the candidate’s ability to think on their feet as well as their ability to write clean, optimized code.

4. Subarray Division

Based on a technique used for searching pairs in a sorted array ( called the “two pointers” technique ), this problem can be solved in just a few lines and judges the candidate’s ability to optimize (as well as basic mathematical skills).

5. The Grid Search 

This is a problem of moderate difficulty and tests the candidate’s knowledge of strings and searching algorithms, the latter of which is regularly tested in developer interviews across all levels.

Common Non-Technical Problem-Solving Interview Questions 

Testing a candidate’s problem-solving skills goes beyond the IDE . Everyday situations can help illustrate competency, so here are a few questions that focus on past experiences and hypothetical situations to help interviewers gauge problem-solving skills.

1. Given the problem of selecting a new tool to invest in, where and how would you begin this task? 

Key Insight : This question offers insight into the candidate’s research skills. Ideally, they would begin by identifying the problem, interviewing stakeholders, gathering insights from the team, and researching what tools exist to best solve for the team’s challenges and goals. 

2. Have you ever recognized a potential problem and addressed it before it occurred? 

Key Insight: Prevention is often better than cure. The ability to recognize a problem before it occurs takes intuition and an understanding of business needs. 

3. A teammate on a time-sensitive project confesses that he’s made a mistake, and it’s putting your team at risk of missing key deadlines. How would you respond?

Key Insight: Sometimes, all the preparation in the world still won’t stop a mishap. Thinking on your feet and managing stress are skills that this question attempts to unearth. Like any other skill, they can be cultivated through practice.

4. Tell me about a time you used a unique problem-solving approach. 

Key Insight: Creativity can manifest in many ways, including original or novel ways to tackle a problem. Methods like the 10X approach and reverse brainstorming are a couple of unique approaches to problem solving. 

5. Have you ever broken rules for the “greater good?” If yes, can you walk me through the situation?

Key Insight: “Ask for forgiveness, not for permission.” It’s unconventional, but in some situations, it may be the mindset needed to drive a solution to a problem.

6. Tell me about a weakness you overcame at work, and the approach you took. 

Key Insight: According to Compass Partnership , “self-awareness allows us to understand how and why we respond in certain situations, giving us the opportunity to take charge of these responses.” It’s easy to get overwhelmed when faced with a problem. Candidates showing high levels of self-awareness are positioned to handle it well.

7. Have you ever owned up to a mistake at work? Can you tell me about it?

Key Insight: Everybody makes mistakes. But owning up to them can be tough, especially at a workplace. Not only does it take courage, but it also requires honesty and a willingness to improve, all signs of 1) a reliable employee and 2) an effective problem solver.

8. How would you approach working with an upset customer?

Key Insight: With the rise of empathy-driven development and more companies choosing to bridge the gap between users and engineers, today’s tech teams speak directly with customers more frequently than ever before. This question brings to light the candidate’s interpersonal skills in a client-facing environment.

9. Have you ever had to solve a problem on your own, but needed to ask for additional help? How did you go about it? 

Key Insight: Knowing when you need assistance to complete a task or address a situation is an important quality to have while problem solving. This questions helps the interviewer get a sense of the candidate’s ability to navigate those waters. 

10. Let’s say you disagree with your colleague on how to move forward with a project. How would you go about resolving the disagreement?

Key Insight: Conflict resolution is an extremely handy skill for any employee to have; an ideal answer to this question might contain a brief explanation of the conflict or situation, the role played by the candidate and the steps taken by them to arrive at a positive resolution or outcome. 

Strategies for Answering Problem-Solving Questions

If you’re a job seeker, chances are you’ll encounter this style of question in your various interview experiences. While problem-solving interview questions may appear simple, they can be easy to fumble — leaving the interviewer without a clear solution or outcome. 

It’s important to approach such questions in a structured manner. Here are a few tried-and-true methods to employ in your next problem-solving interview.

1. Shine in Interviews With the STAR Method

S ituation, T ask, A ction, and R esult is a great method that can be employed to answer a problem-solving or behavioral interview question. Here’s a breakdown of these steps:

• Situation : A good way to address almost any interview question is to lay out and define the situation and circumstances. 
• Task : Define the problem or goal that needs to be addressed. Coding questions are often multifaceted, so this step is particularly important when answering technical problem-solving questions.
• Action : How did you go about solving the problem? Try to be as specific as possible, and state your plan in steps if you can.
• Result : Wrap it up by stating the outcome achieved. 

2. Rise above difficult questions using the SOAR method

A very similar approach to the STAR method, SOAR stands for S ituation, O bstacle, A ction, and R esults .

• Situation: Explain the state of affairs. It’s important to steer clear of stating any personal opinions in this step; focus on the facts.
• Obstacle: State the challenge or problem you faced.
• Action: Detail carefully how you went about overcoming this obstacle.
• Result: What was the end result? Apart from overcoming the obstacle, did you achieve anything else? What did you learn in the process? 

3. Do It the PREP Way

Traditionally used as a method to make effective presentations, the P oint, R eason, E xample, P oint method can also be used to answer problem-solving interview questions.  

• Point : State the solution in plain terms. 
• Reasons: Follow up the solution by detailing your case — and include any data or insights that support your solution. 
• Example: In addition to objective data and insights, drive your answer home by contextualizing the solution in a real-world example.
• Point : Reiterate the solution to make it come full circle.

How to Customize Problem-Solving Interview Questions 

Generic problem-solving interview questions go a long way in gauging a candidate’s skill level, but recruiters can go one step further by customizing these problem-solving questions according to their company’s service, product, vision, or culture. 

Here are some tips to do so:

• Break down the job’s responsibilities into smaller tasks. Job descriptions may contain ambiguous responsibilities like “manage team projects effectively.” To formulate an effective problem-solving question, envision what this task might look like in a real-world context and develop a question around it.  
• Tailor questions to the role at hand. Apart from making for an effective problem-solving question, it gives the candidate the impression you’re an informed technical recruiter. For example, an engineer will likely have attended many scrums. So, a good question to ask is: “Suppose you notice your scrums are turning unproductive. How would you go about addressing this?” 
• Consider the tools and technologies the candidate will use on the job. For example, if Jira is the primary project management tool, a good problem-solving interview question might be: “Can you tell me about a time you simplified a complex workflow — and the tools you used to do so?”
• If you don’t know where to start, your company’s core values can often provide direction. If one of the core values is “ownership,” for example, consider asking a question like: “Can you walk us through a project you owned from start to finish?” 
• Sometimes, developing custom content can be difficult even with all these tips considered. Our platform has a vast selection of problem-solving examples that are designed to help recruiters ask the right questions to help nail their next technical interview.

13. What is an Interface?

An interface is a way of communicating between two objects. The objects can be software or hardware. An interface can be defined in many different ways, but the most common definition is that it is a way for one object to talk to another object. This communication can take many different forms, such as sending data to the other object, receiving data from the other object, or both. An interface can be implemented in many different ways, but the most common way is to use a software class. This class defines the interface and then other classes can use this class to implement the interface. When an object uses an interface, it is saying that it understands how the interface works and can use it to communicate with other objects.

14. What is an abstract class?

An abstract class is a class that is not defined in the source code. Instead, it is defined in a file that contains a definition of the class. The file defines the class by defining all of the properties and methods of the class. However, the class does not have to be defined in the source code. Instead, it can be defined in a separate file that is included in the source code. The file can then be referenced by the source code. This allows the class to be abstract and still be defined in the source code. The main advantage of an abstract class is that it allows other classes to use the class without having to know all of its properties and methods. This makes it possible for other classes to use a class without knowing all of its properties and methods.

15. What is an array?

An array is a data structure that can hold a lot of data. Arrays are used in a lot of different applications, such as databases, spreadsheets, and games. Arrays are made up of different data types, such as numbers, strings, and characters. Arrays are also called indexed structures because they can be accessed by indexing.

Arrays are used in a lot of different applications, such as databases, spreadsheets, and games.

16. What is a constructor?

A constructor is a function that is called when an object is created. A constructor is a function that takes a few arguments the type of object to be created, the initial state of the object, and the name of the class that will contain the object. When an object is created, it is passed to the constructor of the class that contains the object. A constructor can be used in many different ways. For example, a constructor can be used to initialize an array of objects or to initialize a variable that will be used by multiple objects. In these cases, it is important to use a constructor that takes only a few arguments.

17. Define Cin and Cout in C++?

Cin and cout are two important functions in C++ that you should know about. Cin and cout are functions that allow you to read and write data to a stream. The basic syntax of cin and cout is as follows:

• cin(stream) - Read data from the stream.
• cin(stream, value) - Read data from the stream and assign a value to the variable.
• cout(stream) - Write data to the stream.
• cout(stream, value) - Write data to the stream and assign a value to the variable.

The first function cin takes a stream as an argument and reads data from the stream. The second function cout takes a stream as an argument and writes data to the stream. You can use cin and cout to read and write data from a file, a database, or any other source of data.

18. What is artificial intelligence?

21. What are the different OOPS principles?

OOPS, principles are a set of rules and guidelines that organizations can use to ensure that their software is as bug-free as possible. The OOPS principles are:

• Open source- All software should be released under an open-source license, such as the GNU General Public License (GPL) or the Apache License.
• Patent- All software should be released with a patent waiver, such as the USPTO's Patent Promise or the EU's EPO.
• Quality- All software should be developed using quality-assured tools and practices, such as unit testing and code reviews.
• Simplicity- All software should be easy to understand and maintain, and should not require complex configuration or customization.
• Reuse- All software should be reusable so that it can be adapted to new needs without requiring a complete rewrite.

22. Explain the access modifiers?

Access modifiers are a way of specifying which users have access to a resource. Access modifiers are often used to control access to data, files, or other resources. For example, a database might allow only certain users to see the data. Or, a file might be locked down so that only the owner can see it.

23. What do you mean by destructor?

A destructor is a function that is called when an object is destroyed. A destructor is a way to clean up after an object has been destroyed. When an object is destroyed, the memory associated with the object is released. When an object is created, the memory associated with the object is allocated. The destructor is called when the memory associated with the object is no longer needed. The destructor frees up the memory associated with the object and releases it into the environment. When an object is destroyed, it can be very difficult to find out why an object was destroyed.

24. What are the Layers of the OSI Model?

The OSI model is a system-level networking model that describes the topology of a network. The model consists of seven layers: Physical, Data Link, Transport, Network, Application, and Management. Each layer is responsible for providing a specific function. For example, the Physical layer provides connectivity between devices and the Data Link layer is responsible for data transmission. The Transport layer is responsible for routing data and the Network layer is responsible for managing the network. The Application layer is responsible for providing services to the devices on the network and the Management layer is responsible for managing the network. Each layer in the OSI model has a specific purpose and each layer in the OSI model has a specific role to play in the overall system.

25. What is the thread in programming?

The thread is a fundamental concept in programming. It is a way of organizing and managing code so that it can run in parallel. The thread is a way of keeping code running in the background while the main program is running. Threads are used to parallelize tasks and to share resources among multiple threads. When the main program runs, it sends instructions to the thread that is running the task. When the task is done, the thread that was running the task sends instructions to the main program that is waiting for instructions. This process continues until all tasks are done or until one of them crashes or gets interrupted. Threads are a fundamental concept in programming because they allow programs to run in parallel and to share resources. They are also useful for managing memory and CPU usage.

Computer Science Interview Questions for Experienced

1. what is normalization in a database.

Normalization is a process of abstracting and simplifying data. It is a way of making data easier to understand and easier to work with. For example, if you have a data set that contains a lot of numbers, you can normalize it by taking the numbers and breaking them down into smaller pieces, such as by dividing by 10. This makes it easier to work with the data and makes it easier to see trends and patterns. You can also normalize your data by making it more consistent.

2. What is Indexing in DBMS?

Indexing is the process of organizing data in a way that makes it easier to find and access. In a database, the index is a collection of data organized in a way that makes it easy to search and find data. The index consists of a set of key-value pairs that can be used to reference data in the database.

TCP also provides several other functions, such as error detection and recovery, congestion control, and reliability.

5. Explain DNS?

DNS is the acronym for Domain Name System. It's a way of mapping domain names to IP addresses. The IP address is a number that's assigned to each device that connects to the Internet. When you type in a domain name, your computer sends a request to the DNS server, which looks up the corresponding IP address. The DNS server then returns a response that includes the domain name and an associated IP address. This process is called name resolution. DNS is used by most websites and services that use the Internet. It's also used by email services like Gmail and Yahoo Mail, as well as by many online services like shopping sites and online banking services.

6. What are the Application layer protocols?

The Application layer protocols are the protocols that are used to connect applications to the network. These protocols are responsible for transferring data between applications and the network, such as TCP/IP, HTTP, and FTP. The Application layer protocols are also responsible for handling security and privacy. For example, the HTTP protocol is used to transfer data between web pages and the network. The HTTP protocol is also used to protect privacy by encrypting data before it is sent over the network.

7. What are the keys in DBMS?

There are four main keys to a database management system (DBMS): data, integrity, availability, and management. Data is the information stored in the database. Integrity is the ability of the database to prevent the corruption of data. Availability is the ability of the database to provide access to data when needed. Management is the ability of the database to provide tools for administrators and users. In addition, there are many other factors that are important in choosing a DBMS, such as a price, performance, and ease of use.

8. What is Multithreading?

Multithreading is a technique that allows multiple threads to run in parallel on a single processor. This allows multiple tasks to be run in parallel without the need for synchronization. In addition, multithreading can improve performance by allowing tasks to run in parallel without having to wait for each other to finish. For example, it is not appropriate for applications that require high performance or when the processor cannot support more than one thread at a time. Multithreading also has its own set of risks and pitfalls. For example, multithreading can lead to increased system load and increased system resource consumption.

9. What is a Critical Section?

A critical section is a section of code that is crucial to the operation of a program. By accessing critical sections, a program can make changes to the overall functionality of the program without affecting other sections of code. Critical sections are often accessed through functions, methods, and variables. The purpose of a critical section is to ensure that all parts of the program are working properly.

10. What is Deadlock?

A deadlock is a situation where two or more processes are waiting for each other to finish. Deadlock occurs when one process is waiting for another process to finish before it can continue. The process that is waiting will not finish until the other process finishes. This can be a problem if you need to wait for a long time, as this can lead to your system becoming unresponsive.

11. What is Cache?

A cache is a temporary storage location for frequently accessed data. Caches are useful for organizations that need to store large amounts of data in a short amount of time. They can also be used to improve performance by reducing the amount of data that needs to be retrieved from the network. Caches can be used to store data in several different ways. They can be used to store data that is frequently accessed, such as documents or images. They can also be used to store data that is rarely accessed, such as log files or application states. They can also be used to store data that is needed only occasionally, such as temporary files or cookies.

12. What are multiple inheritances in Java?

Multiple inheritances are a way of passing on multiple copies of a particular class or interface to a child's class. This can be useful when you want to make sure that some code is always available to your child's classes. One way to do this is to create a subclass of the parent class, and then provide the child with a copy of the parent class. Another way is to create multiple inheritances in your Java code, and then provide the child with a reference to the parent class. Multiple inheritances are useful for situations where you need to make sure that some code is always available to your child's classes. In Java, multiple inheritances are implemented using the public and private modifiers on a class or interface. When multiple inheritances are present, the public modifier indicates that the class or interface is publically accessible. The private modifier indicates that the class or interface is privately accessible. Multiple inheritances can be useful when you want to make sure that some code is always available to your child's classes.

13. What is a wrapper class?

A wrapper class is a class that inherits from another class and then provides a set of methods and/or properties that are specific to its own purpose. Wrappers are typically used to hide implementation details from the user, allowing the developer to concentrate on the business logic. A wrapper class can be used to hide implementation details from the user, allowing the developer to concentrate on the business logic. Wrappers can also be used to provide a set of methods and/or properties that are specific to their own purpose. The main advantage of wrappers is that they allow you to hide implementation details from the user, allowing you to concentrate on the business logic. The main disadvantage of wrappers is that they can be difficult to maintain.

14. Is string class final?

Yes. The string class is final. This means that you cannot subclass it, and you cannot override its methods. This is a good thing because it means that you can use the string class without worrying about its internal state. There are a few things that you can do to subclass the string class, though. First, you can use StringBuilder to create a subclass of the string class. This class can then override the methods that you need to override to create your own subclass of the string class. Second, you can use StringBuffer to create a subclass of the string class. This class can then override the methods that you need to override to create your own subclass of the string class. Finally, you can use StringBuilder and StringBuffer together to create a subclass of the string class.

15. What is a singleton class?

A singleton class is a class that is defined once and only once. This can be used to reduce the number of classes you need to define in your application, and it can also be used to reduce the complexity of your code. When you define a singleton class, you are declaring that the class is only ever going to be created once. This can be useful if you want to reduce the number of instances that your class will have to create, and it can also be useful if you want to reduce the complexity of your code. Singleton classes are often used when you need to create a single instance of a class, but you don't want that instance to be shared across multiple objects. For example, if you want to create a single instance of a class that represents an image, you might create a singleton class that represents that image.

16. What is cryptography?

Cryptography is the science and art of creating and using codes and ciphers to protect sensitive information from unauthorized access, disclosure, or destruction. Cryptography is used to protect data from unauthorized access, modification, or disclosure. Cryptography can also be used to secure data transmissions, such as e-mail and web browsing. Cryptography also plays an important role in the security of computer networks, such as the Internet. Codes and ciphers are used to encode and decode information. For example, when you type in a password on a computer, the computer uses a code to encrypt the password. When you send an e-mail, you use a code to encrypt the message.

17. What is an Algorithm?

An algorithm is a set of steps that are used to solve a problem. Algorithms are used in a variety of fields, including computer science, mathematics, and engineering. An algorithm is a set of instructions that tells a computer how to perform a task. Algorithms are used to solve problems such as sorting data, searching for patterns in data, and performing calculations. Algorithms are used in many different fields, including computer science, mathematics, and engineering. An algorithm is a set of instructions that tells a computer how to perform a task.

18. What is the World Wide Web?

The World Wide Web (or WWW) is a collection of interconnected data networks that enable people to share information, documents, and programs across the Internet. The web is made up of hundreds of different websites, each of which contains information about a particular topic or subject. These websites are organized into a hierarchy called a “web page” that describes the content of the page and links to other pages. Web pages can be written in many different languages, and they can be organized in many different ways, including using tabs and links. The web is a powerful tool for sharing information because it enables people to easily access information from anywhere on the planet. For example, you can access information about any topic you want from any computer or device that has Internet access. You can also use the web to share documents and programs with other people who have access to the same devices as you do.

Top 20 Problem Solving Interview Questions (Example Answers Included)

Mike Simpson 0 Comments

By Mike Simpson

When candidates prepare for interviews, they usually focus on highlighting their leadership, communication, teamwork, and similar crucial soft skills . However, not everyone gets ready for problem-solving interview questions. And that can be a big mistake.

Problem-solving is relevant to nearly any job on the planet. Yes, it’s more prevalent in certain industries, but it’s helpful almost everywhere.

Regardless of the role you want to land, you may be asked to provide problem-solving examples or describe how you would deal with specific situations. That’s why being ready to showcase your problem-solving skills is so vital.

If you aren’t sure who to tackle problem-solving questions, don’t worry, we have your back. Come with us as we explore this exciting part of the interview process, as well as some problem-solving interview questions and example answers.

What Is Problem-Solving?

When you’re trying to land a position, there’s a good chance you’ll face some problem-solving interview questions. But what exactly is problem-solving? And why is it so important to hiring managers?

Well, the good folks at Merriam-Webster define problem-solving as “the process or act of finding a solution to a problem.” While that may seem like common sense, there’s a critical part to that definition that should catch your eye.

What part is that? The word “process.”

In the end, problem-solving is an activity. It’s your ability to take appropriate steps to find answers, determine how to proceed, or otherwise overcome the challenge.

Being great at it usually means having a range of helpful problem-solving skills and traits. Research, diligence, patience, attention-to-detail , collaboration… they can all play a role. So can analytical thinking , creativity, and open-mindedness.

But why do hiring managers worry about your problem-solving skills? Well, mainly, because every job comes with its fair share of problems.

While problem-solving is relevant to scientific, technical, legal, medical, and a whole slew of other careers. It helps you overcome challenges and deal with the unexpected. It plays a role in troubleshooting and innovation. That’s why it matters to hiring managers.

How to Answer Problem-Solving Interview Questions

Okay, before we get to our examples, let’s take a quick second to talk about strategy. Knowing how to answer problem-solving interview questions is crucial. Why? Because the hiring manager might ask you something that you don’t anticipate.

Problem-solving interview questions are all about seeing how you think. As a result, they can be a bit… unconventional.

These aren’t your run-of-the-mill job interview questions . Instead, they are tricky behavioral interview questions . After all, the goal is to find out how you approach problem-solving, so most are going to feature scenarios, brainteasers, or something similar.

So, having a great strategy means knowing how to deal with behavioral questions. Luckily, there are a couple of tools that can help.

First, when it comes to the classic approach to behavioral interview questions, look no further than the STAR Method . With the STAR method, you learn how to turn your answers into captivating stories. This makes your responses tons more engaging, ensuring you keep the hiring manager’s attention from beginning to end.

Now, should you stop with the STAR Method? Of course not. If you want to take your answers to the next level, spend some time with the Tailoring Method , too.

With the Tailoring Method, it’s all about relevance. So, if you get a chance to choose an example that demonstrates your problem-solving skills, this is really the way to go.

We also wanted to let you know that we created an amazing free cheat sheet that will give you word-for-word answers for some of the toughest interview questions you are going to face in your upcoming interview. After all, hiring managers will often ask you more generalized interview questions!

Top 3 Problem-Solving-Based Interview Questions

Alright, here is what you’ve been waiting for: the problem-solving questions and sample answers.

While many questions in this category are job-specific, these tend to apply to nearly any job. That means there’s a good chance you’ll come across them at some point in your career, making them a great starting point when you’re practicing for an interview.

So, let’s dive in, shall we? Here’s a look at the top three problem-solving interview questions and example responses.

1. Can you tell me about a time when you had to solve a challenging problem?

In the land of problem-solving questions, this one might be your best-case scenario. It lets you choose your own problem-solving examples to highlight, putting you in complete control.

When you choose an example, go with one that is relevant to what you’ll face in the role. The closer the match, the better the answer is in the eyes of the hiring manager.

EXAMPLE ANSWER:

“While working as a mobile telecom support specialist for a large organization, we had to transition our MDM service from one vendor to another within 45 days. This personally physically handling 500 devices within the agency. Devices had to be gathered from the headquarters and satellite offices, which were located all across the state, something that was challenging even without the tight deadline. I approached the situation by identifying the location assignment of all personnel within the organization, enabling me to estimate transit times for receiving the devices. Next, I timed out how many devices I could personally update in a day. Together, this allowed me to create a general timeline. After that, I coordinated with each location, both expressing the urgency of adhering to deadlines and scheduling bulk shipping options. While there were occasional bouts of resistance, I worked with location leaders to calm concerns and facilitate action. While performing all of the updates was daunting, my approach to organizing the event made it a success. Ultimately, the entire transition was finished five days before the deadline, exceeding the expectations of many.”

2. Describe a time where you made a mistake. What did you do to fix it?

While this might not look like it’s based on problem-solving on the surface, it actually is. When you make a mistake, it creates a challenge, one you have to work your way through. At a minimum, it’s an opportunity to highlight problem-solving skills, even if you don’t address the topic directly.

When you choose an example, you want to go with a situation where the end was positive. However, the issue still has to be significant, causing something negative to happen in the moment that you, ideally, overcame.

“When I first began in a supervisory role, I had trouble setting down my individual contributor hat. I tried to keep up with my past duties while also taking on the responsibilities of my new role. As a result, I began rushing and introduced an error into the code of the software my team was updating. The error led to a memory leak. We became aware of the issue when the performance was hindered, though we didn’t immediately know the cause. I dove back into the code, reviewing recent changes, and, ultimately, determined the issue was a mistake on my end. When I made that discovery, I took several steps. First, I let my team know that the error was mine and let them know its nature. Second, I worked with my team to correct the issue, resolving the memory leak. Finally, I took this as a lesson about delegation. I began assigning work to my team more effectively, a move that allowed me to excel as a manager and help them thrive as contributors. It was a crucial learning moment, one that I have valued every day since.”

3. If you identify a potential risk in a project, what steps do you take to prevent it?

Yes, this is also a problem-solving question. The difference is, with this one, it’s not about fixing an issue; it’s about stopping it from happening. Still, you use problem-solving skills along the way, so it falls in this question category.

If you can, use an example of a moment when you mitigated risk in the past. If you haven’t had that opportunity, approach it theoretically, discussing the steps you would take to prevent an issue from developing.

“If I identify a potential risk in a project, my first step is to assess the various factors that could lead to a poor outcome. Prevention requires analysis. Ensuring I fully understand what can trigger the undesired event creates the right foundation, allowing me to figure out how to reduce the likelihood of those events occurring. Once I have the right level of understanding, I come up with a mitigation plan. Exactly what this includes varies depending on the nature of the issue, though it usually involves various steps and checks designed to monitor the project as it progresses to spot paths that may make the problem more likely to happen. I find this approach effective as it combines knowledge and ongoing vigilance. That way, if the project begins to head into risky territory, I can correct its trajectory.”

17 More Problem-Solving-Based Interview Questions

In the world of problem-solving questions, some apply to a wide range of jobs, while others are more niche. For example, customer service reps and IT helpdesk professionals both encounter challenges, but not usually the same kind.

As a result, some of the questions in this list may be more relevant to certain careers than others. However, they all give you insights into what this kind of question looks like, making them worth reviewing.

Here are 17 more problem-solving interview questions you might face off against during your job search:

Question 1 of 25

What has been the biggest mistake you have made when delegating work? The biggest success?

How to Answer

Answer example.

Delegation is a key skill any worker needs to possess. It is even more important for managers and supervisors. Talking about what you've learned from your mistakes and successes while delegating a task will demonstrate your growth potential. When discussing a mistake, make sure you talk about what you learned from it and what you will avoid doing in the future.

"My biggest success when delegating work was assigning an inexperienced coder the job of creating code for a complex task. I knew this was a stretch for them, but I also knew that it would help them develop new skills if they were successful. I assigned one of the more experienced coders to work with them. The individual was able to complete the task and learn some new coding skills along the way. Ironically, a similar situation was my biggest failure. I tried to do the same thing with another new coder, and they could not complete the code. The difference between these two situations was that I did not assign a mentor, so the individual had to work on their own in the latter. Not only did they fail in developing the code, but they became discouraged and quickly left the company for another job. What I learned from this was that I need to make sure my staff have a coach or manager who can help them be successful when I assign stretch goals to them."

2. What is a process and a thread, and how are they used in your profession?

This technical question asks you to define and compare two very similar terms. Knowing the answer to questions like this will demonstrate your qualifications as a computer scientist. It is highly recommended that you review the terms, technologies, concepts, and processes used in your job before attending an interview. Interviewers are likely to ask about all of these.

"A process and a thread are very similar in concept. In the execution of a program, both define the sequences and code a program executes. The difference between a process and a thread is that a thread is a segment of a process. Processes can have several different threads which define how the program executes. Another difference is that processes will take longer to terminate than individual threads. Finally, threads can share memory while processes can't."

3. What are the most popular operating systems, and how experienced are you at working with them?

Even though you may only use one computer operating system in your work as a computer scientist, you should be familiar with all of the operating systems available in the industry. This will demonstrate your adaptability and your ability to move between operating systems as required. Organizations will continually adopt new technologies that better meet their computing needs. These can include new processers, operating systems, and programming languages. Being able to switch between these will increase your value as a computer scientist and help you advance your career in the field.

"The most popular operating systems in today's IT industry include Microsoft Windows, OSX, and Linux. I've worked with each of these in previous positions and am very familiar with all of them. I also know how to recompile code so that it can work with the different operating systems. I've done a lot of work adapting internal programs in order for them to have a similar look and feel despite the individual operating systems' nuances. I have also created reactive applications that work on both desktop and laptop computers and that also adapt to the interfaces of mobile devices."

4. Describe what a chipset is.

Throughout an interview for a position in the field of computer science, you will be asked a great many technical questions. Remember that technical questions ask you to define a term, process, or concept and discuss how it is used in your work. Technical questions can range from very basic to extremely difficult. Typically, an interviewer will start with basic questions that are easy to answer. As the interview progresses, the subjects of the questions will become more difficult and specific. Continue to answer the questions briefly and to the point.

"The chipset is a collection of integrated circuits used to help the computer communicate with its various components. Chipsets are individual processers that perform specific functions. These include the CPU, a graphics chip, memory, and other chips that control other devices that interface with a computer. Chipsets can control items such as keyboards and mice, USB drives, and audio input and output devices."

5. What is an interface in the context of its use in Java?

The terminology used in the computer science profession can have different meanings depending on the context i which it is used. This question is an example of this. In normal computer language, interface is the connection between the computer hardware and the operator. However, this question asks you to define interface as it is used within the context of a programming language. Knowing these nuances and answering the question appropriately will help demonstrate your qualifications for this position.

"Within the context of Java, interface is a reference type. This is similar to classes that are used in other programming languages. However, the one difference is that within Java, interface also includes abstract methods."

6. What are the most commonly used processors in modern computers?

Employers expect job candidates to be up-to-date on current trends in technology used in the computer science profession. You should be able to name the current processors used as well as the latest versions of operating systems, popular software applications, and other technology that has been recently released from manufacturers. Research the company or organization prior to your interview to determine what technology they use. When providing examples of current technology, you should reference the same technology you discovered in your research.

Written by William Swansen on November 4th, 2020

"The most popular processors in use in today's computers are from Intel and AMD. The latest releases from Intel include the Core i5, the Core i7, and the Core i9. AMD's most recent processors are the Ryzen 5 and 7."

7. What are the differences between primary and secondary memory?

This technical question is meant to determine your knowledge of the subject and how you use it to perform your job. The best way to prepare for an interview as a computer scientist is to thoroughly understand your profession's technical terms. You should be able to identify, define, and talk about how these items are used. Describing unique uses and innovative ways to employ the concepts will distinguish you from other candidates.

"Primary memory is the main memory used by the CPU in a computer. It consists of ROM and RAM and is stored on integrated circuit chips. Secondary memory refers to storage that is external to the computer's motherboard. Examples of secondary memory include hard drives, DVDs, USB memory sticks, and other devices where memory is stored externally and can be removed from the computer if necessary."

8. What is multiple inheritance? Can you discuss its advantages and disadvantages?

This is a challenging and complex technical question. As the interview progresses, the questions will become more difficult and detailed. This indicates that the hiring manager is gaining confidence in your qualifications and is willing to explore your background in more depth. Continue to answer these questions just as you did the easier ones, briefly and to the point. Also, anticipate follow-up questions.

"Multiple inheritances refer to classes. Specifically, a situation where one of the classes inherits arguments from multiple super-classes. The advantage is that this type of class can inherit more than one class's functionality and, therefore, can be more flexible. The disadvantage is that using more than one super-class may create arguments that conflict with each other due to them both using the same descriptors."

9. Please describe the difference between C and C++ and in which language you prefer to code.

This is a hybrid technical and operational question. It starts by asking you to discuss two types of programming languages and then asks which one you use in your work. Interviewers can create any type of question they want to while attempting to collect the information they need to make a hiring decision. There are no hard and fast rules for interview questions. However, identifying the types of questions will help you understand what the interviewer is seeking to learn and how you can format your response to their question.

"C is based on a very structured programming protocol, while C++ is an object-oriented programming language. Since C++ is easier to use and more flexible, I prefer programming in this language. Fortunately, code written in C can be recompiled to work with C++ programs."

10. Please discuss default constructors and conversion constructors.

This is a technical question which requires that you talk about two tools used in your profession. Technical questions are best answered directly and succinctly. You should be prepared for follow-up questions. The best way to prepare for an interview that involves technical questions is to review the terms, processes, and operations used in your profession before the interview. It is also good to research the company to understand the technology that it uses to be prepared to answer questions about it.

"A default constructor will either have no arguments or, if it does have arguments, they will be the default values. On the other hand, a conversion constructor can accept an argument that is different from the default. It uses the argument to create conversion rules for a class."

11. Can you describe what a class and a super-class are and how they differ?

This is a technical question. Technical questions ask you to define a term and then describe how you use it in this job. Like operational questions, technical questions are best answered briefly and directly. You should anticipate follow-up questions when providing your answer.

"A class is used to define the characteristics of an object used in programming. A class will inherit the state and behavior from all its ancestors, which are the classes that preceded it. A super-class refers to the class's direct ancestor or the class that just preceded it as well as all the classes that follow it."

12. What programming languages do you prefer to work with? Why?

This is an example of an operational question. Operational questions help the interviewer understand how you go about doing your job. While interviewing for a role as a computer scientist, you can expect a wide range of question types, including behavioral, situational, technical, and operational. Operational questions are best answered briefly and directly. The interviewer will ask you a follow-up question if they need additional information.

"While I am adept at several different programming languages, the one I prefer the most is Python. This is because it's easy to learn and has a great many libraries I can leverage. This helps to reduce the time it takes to code and enables me to be more creative and efficient."

13. What do you do when your schedule is suddenly interrupted? Give an example.

No one likes to be interrupted when they are working, but it happens. The key is managing the interruptions and succeeding in staying on task in order to complete your work on time. Since the question asks for a specific example, you should have a story prepared and integrate it into your answer to this question.

"While I don't like interruptions, I do know they happen. My strategy is to pause my work and manage the interruption as effectively and efficiently as possible. If I can't resolve the issue immediately, I commit to doing it later so I can get back to my immediate task. A good example of this was when I was writing a piece of code that demanded a great deal of concentration. I was interrupted several times an hour by my team to help resolve minor, unimportant issues. I pulled the team together, let them know that I needed to focus for at least four hours and that I would address their concerns after that. I also assigned one of my supervisors to be their point of contact for any concerns that couldn't wait."

14. Why do you want to work for our software company?

This is a typical question you will likely receive early in the interview. By the time you've been invited to the interview, the organization has already verified your qualifications for the position. The interview is meant to confirm these qualifications and discover how well you will fit into their company. Organizations prefer people who are passionate about both the work they do and the companies for which they work. Your answer to this should support both of these.

"When searching for opportunities where I could apply my computer science background, your company kept rising to the top of the list. I admire the work you do and your leadership in this industry. I have spoken to several current and former employees. They are very enthusiastic about the work environment, the flexibility they have to explore new ideas, and the collaborative and diverse work culture your organization promotes. I would be honored to become part of your company and to contribute to your ongoing success."

15. What would your goals be as a computer scientist working for our company?

Hiring managers are looking for candidates who are both qualified for the job and willing to take initiative. When preparing for an interview, you should understand the company's business objectives and challenges. You should then formulate a plan to resolve these and be ready to discuss it during the interview. The interviewer will not fault you if your plan is not perfect or even something they are thinking about. The point is to have a plan and be able to communicate it effectively.

"Based on the research I've done, I noted that your company has been challenged with a shrinking customer base and lower demand for your products. One reason behind this is that you may not have a clear understanding of your customer preferences or the type of products they are planning to purchase. If hired as a computer scientist, I propose a revamping of your customer resource management system so that your salesforce can effectively interface with the customers. They could recommend new products that would align with the customer's needs, discover opportunities for product upgrades, and recommend products related to those they had already purchased. This would help you with customer retention as well as increase your revenues."

16. Tell me about something you are proud of regarding creating a new function or model in your coding.

This question is asking you to brag about something. Most people are very humble and find it difficult to promote themselves or talk about their significant achievements. You need to overcome this tendency during an interview. There's nobody else in the room who will speak on your behalf, so you have to do it. When answering this question, you should identify a function or model in the coding that aligns with the role for which you are interviewing. The research you conduct before the interview will help you accomplish this.

"The function I am most proud of in my coding is a voice recognition module in a network management dashboard. It allows the systems administrators to make requests for information in the dashboard hands-free. This comes in handy when they are away from the computer terminal or are actively working on the network and have tools or measuring equipment in their hands."

17. Have you come across a problem that you could not solve? How did you handle the problem?

Your initial reaction to this question might be to state that you have never come across a problem you couldn't solve. However, this would make you unbelievably unique. Everyone has encountered a situation they couldn't resolve, at least by themselves. Being able to describe a problem, including how you came to solve it, will demonstrate humility, honesty, and innovation. This is the type of question you should anticipate, so have an example ready.

"It is rare, but I do occasionally come across a problem that I can't solve by myself. A good example of this was a recent project in which we were updating our network infrastructure. One router within the network wasn't responding, and my team and I could not identify it. We sought assistance from the network support team that had an analytics tool we were not familiar with. In a matter of minutes, they had identified and repaired the misbehaving router. When I encounter difficult situations, I don't hesitate to seek outside assistance from people who are better qualified to handle a specific issue than I am."

18. Who has been the greatest influence on you thus far in your career as a computer scientist?

This is a general question an interviewer might ask to better understand you as a person. In addition to being qualified for the job, they are interested in whether you will fit into their organization and contribute to its culture. Identifying who has had a great influence on you tells a lot about you and gives them insight into your background as a computer scientist.

"The person who has had the greatest influence on me thus far is Elon Musk. I admire his innovative thinking and the way that he can inspire others to achieve their best. His outlandish ideas make sense once he describes why he thinks they can be achieved and what it will take to accomplish them. I try to apply his philosophy and innovative thinking in my work."

19. How do you stay current on new programming updates and techniques?

The computer industry moves at a rapid pace. Updates occur daily, and staying on top of them is a real challenge. You should have a specific plan to keep yourself abreast of any changes in the market and be able to describe this to the interviewer.

"One of the things I pride myself on is being current on the developments occurring in the programming space. I do this by taking time out of my day to read industry publications and follow the most popular bloggers. I also attend regular seminars, user group meetings, and other industry events, and I go to national conventions at least twice a year. Additionally, I spend a lot of time with hardware and software vendors as well as my peers in the industry, discussing what is new on the market."

20. Tell me about a time when you did something completely different from the plan. Why did you go that route?

This is a behavioral question. Behavioral questions ask you to tell a story about an incident in the past and how you reacted. Interviewers will ask behavioral questions to gauge how you will react to similar situations in the future. Behavioral questions are best answered using the STAR framework. You state the Situation, describe the Task you had to complete, talk about the Actions you took, and then discuss the Results you achieved.

"In my last job, I was asked to help design and implement a new customer resource management system. Management recommended we work with the premier vendor in this space and expected us to complete the project within three weeks. I was aware of a new product that had come to the market and took a chance with it. We were able to design and implement the CRM within two weeks, and the features and performance exceeded the specifications with which we were originally working. Management initially reacted negatively when I had not selecting their vendor. However, after viewing the system and seeing it perform, they were happy with the results."

21. Tell me about a situation in which attention to detail was particularly important when accomplishing an assigned task.

Attention to detail is important in any job, but especially in the role of a computer scientist. Missing important details could result in software not functioning properly or processes not producing the intended results. This is in the form of a behavioral question, so you should use the STAR framework when you respond. Keep your answer positive, demonstrate the results of paying attention to the details, and emphasize the outcome.

"One of the skills I've developed while preparing for this role is paying attention to details. During a recent project, this came in handy. We were integrating a new software package into the company's HR Department. During the installation, I noted that an important field was left out of a form that was critical to the department's operations. If this had gone unchecked, it would have resulted in the HR Department having to reconstruct thousands of records. Fortunately, we were able to address this early and avoid any rework. This helped the company avoid significant costs, prevented delays in the software implementation, and resulted in a much more functional HR process. It also emphasized the need to pay attention to detail in everything I do."

22. When is the last time you had a disagreement with a peer? How did you resolve the situation?

This is a behavioral question. Behavioral questions seek to understand how you would act in a specific situation. These types of questions are best answered using the STAR framework. You state the Situation, describe the Task you are trying to achieve, talk about the Actions you took, and then discuss the Results you achieved. Make sure you emphasize the results and share that they are similar to what you will be expected to accomplish in this role.

"While it is rare, I do occasionally have disagreements with my coworkers. An example of this is when one of my peers thought we should use a different manufacturer's collaboration tool. My concern was that the tool had not been properly vetted and may not interface with the company's current software products. When it became clear that we would not be able to reach an agreement, I suggested that we meet with our manager to put forth our recommendations. He agreed, and we had a meeting shortly after that. The manager felt both recommendations were valid but chose to go with my coworker's. This turned out to be the right choice. What I learned from this was that I need to keep an open mind and that when I reach an impasse with a coworker, it is the role of the manager to intervene and resolve it."

23. Give me an example of when you had to go above and beyond the call of duty to get a job done.

Employers are always looking for candidates who are willing to go above and beyond their job description to accomplish tasks that are not their primary responsibility. Demonstrating that you have done this in the past will help set you apart from other candidates and show the interviewer that you are a team player. Make sure you pick an example aligned with the type of work you will be doing in this role.

"I am always looking for opportunities that allow me to do more than what is expected. This contributes to the company's success and also allows me to advance within the organization. In my last job, I noticed that one of my coworkers was struggling to complete a project on time. I offered to assist them and suggested that we schedule some time in the evening to focus on the project. We spent two weeks collaborating and were able to finish the project early with the outcomes exceeding the management team's expectations. I firmly believe this was one of the reasons I was promoted to a supervisory position."

24. Tell us about a time when you were particularly effective in prioritizing tasks and completing a project on schedule.

This is an example of an operational question. Operational questions help the interviewer understand how you go about doing your job and what you have achieved in prior positions. They want to ensure that you are capable of doing the job and that your achievements mirror the work you will be doing at their company. Again, the research you conducted before the interview will help you select the achievements that best demonstrate your qualifications for this role.

"In my most recent job, I was tasked with analyzing the company's operations and creating a dashboard which would allow managers to quickly understand how the company was doing and what - if any - changes needed to be made to make the manufacturing process more efficient. I succeeded by first analyzing their current operations and noting the company's software applications used to manage their processes. I then worked with a vendor to integrate the software into a single reporting structure that could be viewed through a consolidated dashboard. This helped the managers to quickly see how they were doing and to make adjustments in real-time. This resulted in efficiencies increasing by 20% and lead-times decreasing by 5%."

25. What do you know about us?

Hiring managers expect you to arrive at the interview knowing a great deal about the position, the company, their industry, achievements, and challenges. These are the things that they will likely ask about during the interview to ensure that you can contribute to their operational and business objectives. Conducting thorough research before the interview is critical to being able to answer these types of questions. You can find the information on the company's web site, industry-related news, by contacting current and former employees, and other online resources.

"While preparing for this interview, I did a great deal of research and learned quite a bit about your company. I understand that you are an industry leader due to the company's leadership and the innovative advancements you have introduced. I noted that your market share increased by 20% last year and that you are forecasting sales to grow by 10% this year. Glassdoor rates you as one of the best companies to work for in this area. The employees I spoke with rave about the work environment and how you allow individuals to perform at their best while providing them the resources they need to achieve their goals. This is exactly the type of company I would like to work for."

Prepare for a Software or Technical Interview

Planning to interview for a software or technical position? Refer to these tips and resources to help you prepare!

Interview Formats

What, exactly, is a software or technical interview? Depending on the field and the position, these interviews may require you to

• Create a PowerPoint presentation on a tech topic
• Write code in real-time and/or do an on-the-spot coding test
• Compete a technical problem in a group and present to a panel
• Work out a tech problem on a whiteboard in front of a group

How to Prepare

Lock in the fundamentals.

In addition to more traditional behavioral questions, a technical interview will cover your knowledge of computer science. Depending on the job , this could be coding, data structures, algorithms, systems design, big O notation, etc. Refer to your coursework to refresh your memory on the basics.

familiarize yourself with the format and types of questions

First, if the recruiter has sent you material on preparing for the interview, be sure to review it closely. Also, check to see if the company has interview prep information on its website. If you are not sure of the format, ask the recruiter.

Questions will focus on the types of skills you’ll be using on the job. They can range from the core fundamentals to higher-level principles.

Many technical questions are based on your own experience. Did you create a game for a class project and put it on your resume? Be ready to talk about your technical tasks, challenges, and contributions.

Although some companies are entirely removing them from their interview process, you might receive a brainteaser during technical interviews. These questions assess your problem-solving abilities, comfort with ambiguity, and quantitative skills. Share your thought process and problem-solving approach out loud, and try to enjoy the challenge.

How to Practice

Most interviewers want to hear you explain your thought process while working through a problem. This gives them insight into your personality, problem-solving skills, and ability to work under pressure. There are many ways you can practice doing this:

• Ask a friend with a technical background to act as your mock interviewer. Practicing and explaining out loud is a great way to prepare and build confidence.
• Get involved in competitive programming and hackathons and make open-source contributions.
• Be prepared to thoroughly explain any technical projects listed on your resume.

Interview Tips

Don’t dwell on mistakes.

Be comfortable asking questions and asking for clarification. If you make a mistake, don’t let it affect the rest of the interview. You’ll have the opportunity to answer many questions and the interviewer will often forgive a single mistake. When something goes wrong, move on and focus on the rest of the interview. If you don’t know the answer to a particular question, just be honest about it. Try to engage the interviewer so you can learn more about the topic and/or explain where you could find the answer.

Use the Interview to Show Your Passion for Tech

By demonstrating your passion for coding and creating new programs, you are also showing why you are the right candidate for the position. Related extracurricular activities are a great way to show this passion. “The number one thing I look at on resumes is extra-curricular activities,” says former Google engineer Paul Tyma in a blog post. He adds, “I want to hire engineers that I want to work with. And those engineers are passionate about cool algorithms, slick code, and new ideas. They do that stuff in their spare time—it’s not just a job, it’s what they do because they love it.”

Be Prepared for a Lengthy Interview Process

The tech interview process may take several weeks and involve multiple interviews. (Recruiters will often clarify this process in advance.) After the initial phone screening, you might meet with engineers and managers in the days or weeks to come.

Don’t Forget to Prepare for Traditional/Behavioral Questions

Employers often say that students are so concerned about the technical interview that they haven’t thought through answers to common questions like “Tell me about yourself?” or “Why are you interested in this job?” Read through our tips on common interview questions and practice behavioral questions with a CCE career counselor .
