Answering Technical Interview Questions

Introduction to Technical Questions

Technical questions are an essential part of the interviewing process.  These questions are designed to test a candidate's abilities as they pertain to the position they're applying for.  They can be used to test general knowledge within that industry or to determine a candidate's "hard" skills. Overall, technical questions will let the interviewer know if the candidate is able to perform the day-to-day operations associated with that position. 

When answering technical questions, candidates may be expected to apply their knowledge to real-world scenarios and are often assessed on the logical process they utilize to solve a problem. 

Why Do Interviewers Ask Technical Questions?

Interviewers ask technical questions because it helps them separate qualified candidates from unqualified ones.  It's estimated that it costs 10-20% of a new employee's salary to train them, so interviewers want to make sure they select the right hire to invest in. 

These questions can range from a broad understanding of the industry to inquiries about specific problems you will see on the job. 

What Do Interviewers Expect When Asking Technical Questions?

When interviewers ask technical questions, they expect candidates to show them that they are technically qualified for that position. Therefore, when you are answering technical questions, you should:

Give a detailed account of your thought process

The interviewer wants to know how you will react to certain obstacles that may come up in the workplace.

Communicate clearly

Technical questions aren’t just about what you know; they’re also about how you communicate that knowledge. 

Show your enthusiasm

Not only do you want to show the interviewer that you are qualified for the job, but you also want to show them you’re enthusiastic about the industry you’re in. 

How to Prepare for Technical Questions

“When done properly, the questions you get in a technical interview are ones that you won’t have heard before.” - Gayle McDowell, “Cracking the Code’

While there are some common technical questions that you can expect to be asked, the interviewer will also have done their best to come up with questions you haven’t heard before. 

Follow these easy steps to make sure you’re ready:

Make sure your foundation is steady

Go back to the basics. Taking a couple of hours to go over your foundational knowledge will help you feel more confident going into the interview.

Do your research

Go back to the original job post and review the requirements and day-to-day responsibilities since this is what the interviewer will test your knowledge on.


The best way to improve your interviewing skills is to take practice mock interviews.

Other Interview Question Types

Technical questions aren’t the only kind of questions that get asked frequently. Here are three more common question types you can expect to be asked during an interview and what you can do to prepare for them!

We go into more detail about the other types in the premium version:

Case Study

Key Skills Involved 

  • Similar to logic questions, case studies require you to perform in-depth analyzations to solve a hypothetical business problem or scenario.

Example Question

  • “Do you think we should enter a new market? If so, what strategy should we utilize?”

Pro Tip

  • These kinds of questions are usually complicated and specific. It’s not unreasonable to take a bit of time to work out an answer, so don’t rush yourself.

Company Knowledge

Key Skills Involved 

  • An interviewer may use these questions to evaluate how much you have researched about the company. This is a good way to express your interest in the company.

Example Question

  • "Why are you interested in working here?"

Pro Tip

  • Show that you have done your homework and understand the company's mission and future. Think about how your goals correlate, and explain what excites you most about the company.


    Key Skills Involved 

    • Used by interviewers to evaluate your background, experience questions give insight into a candidate’s skills and abilities. Interviewers will often ask questions about past projects or situations.

    Example Question

    • “What were your day-to-day responsibilities at your last job?”

      Pro Tip

      • It’s a good idea to have a few specific situations in mind for different scenarios. That way, you can choose one quickly and already be prepared to talk about it.

      Illegal and Inappropriate Questions

      • “How old are you?” 
      • “Are you married?” 
      • “Do you plan on having children anytime soon?” 

      While these questions may seem innocent, they are actually illegal to ask during an interview. 

      Although it may seem like the interviewer is just trying to get to know you, answering questions about these topics can actually hurt your chances of getting the job. 

      How to Respond to Illegal Questions

      If an inappropriate question comes up, there are a few ways you can reply that won’t reveal personal information about yourself. You can:

      Redirect the question to the interviewer

      One of the most effective ways to handle an illegal question is redirecting it back to the interviewer. Not only does it draw their focus off of you and onto themselves, but it also gives you more information about the person interviewing you. This helps to distract the interviewer from their original question.


      Illegal Question: “Do you have any children?”

      Response: “I’m committed to a career regardless of my family status. I also noticed the company does a great job promoting a healthy work-life balance for employees. What has your experience been with that?”

      Avoid answering the question

      Avoiding answering the question in a graceful manner could be your best bet when handling an inappropriate question. 

      Keep your answers broad

      Sometimes there’s just no way to avoid the question — when this happens, keep your answers broad and vague.

      Be direct

      Sometimes, a situation calls for a direct approach. You are completely within your rights to tell the interviewer that you don’t think a question is appropriate.

      Address the

      Consider what the interviewer may really be asking. 

      Keep in mind that sometimes an interviewer may be inexperienced or unaware that the questions they are asking are inappropriate. It’s best to be diplomatic in your answers and attempt to keep the interview moving. 

      Additional examples of illegal questions and details about how to respond to them are provided in the premium version of the training program.
