11 min read

You’ve worked hard to build your resume and expand your expertise in your career field. Now comes the toughest hurdle: the job interview. 

The interview process can be daunting even if you’re a great candidate. It’s easy to slip up on a tricky interview question and give an unsatisfactory response. That’s why you should prepare for your next interview by reviewing common questions and answers — especially if you’re in a technical field like software engineering, computer science, web development, or cybersecurity. 

Types of Interview Questions

Job interviews involve an array of questions to discover different aspects of a candidate, such as background, knowledge, and values. Questions may aim to ascertain your expertise on a specific subject or determine your aptitude for handling stressful situations.

Many tech companies ask a variety of interview questions when hiring for a tech job beyond simply understanding your technical skills in the information technology field.

What are the different types of interview questions? Behavioral, situational, education, and technical. Here’s a brief summary of all four types of questions, why interviewers ask them, and sample questions as examples.

Behavioral Questions

Behavioral questions help stakeholders guage your soft skills. They’ll appraise things like time management, teamwork, dependability, self-awareness, problem-solving, and communication skills based on how you’ve handled past situations.

Behavioral interview questions may include:

  • Describe a time when you’ve experienced conflict with a coworker. How did you resolve it?

  • When have you disagreed with a boss? Did you voice your dissent?

  • Tell me about a time when you’ve failed to accomplish a goal. What did you learn?

  • What do you do when you face a challenging project or situation?

  • What is your approach to meeting deadlines for multiple concurrent projects?

Your answers to such behavioral questions will inform the interviewer if you would be a good fit within their company culture and with fellow team members as a new hire. For management positions, these would also assess your leadership skills and project management capability.

Situational Questions

Situational questions determine how interviewees might behave in future situations they’d encounter at the company. These queries are hypothetical scenarios that may be common in this workplace or important to the evaluator. 

A good way to answer these is by connecting the hypothetical scenario to an actual situation you’ve encountered in the past and talking through your thought process.

Situational questions might include:

  • What would you do if your boss gave you a task that you don’t believe can be completed by their deadline? 

  • You’re working alongside a coworker on a joint project, but your colleague isn’t pulling their weight. How would you handle this situation? 

  • How would you handle an angry phone call from a client who was displeased about our product or services?

  • You find out a coworker has been lying about the work they’ve been doing. What would you do with this knowledge?

  • You need to make a good impression on a client. How do you prepare for the meeting?

  • Your workload has been rapidly increasing beyond what you can handle, and you’ve just missed a big deadline. What do you do?

You responses will help the interviewer determine how well you’ll thrive in their company. These questions can also give you insights into a company’s culture. E.g. If the interviewers focus on heavy workloads and tight deadlines, be sure to bring it up when it’s your turn to ask questions — how does leadership ensure their expectations are manageable?

Education Questions

Your academic background can be very important in some career fields, so you may be asked education questions during an interview. These questions put the spotlight on your school experience and any professional instruction you’ve received. 

You may discuss your schooling, grades, major, teachers, and future learning goals. Be ready identify their relevance to the job and what you can bring to the company. 

Education questions include:

  • What made you choose the college or technical school you attended?

  • What certifications do you hold?

  • How has your coursework prepared you for this position?

  • What professional development opportunities have you pursued?

  • How do you stay informed on the latest advancements and changes in this field?

  • Do you intend to return to school in the future and continue your education? 

Your responses will inform the interviewer of how your educational background pertains to the job position you’ve applied for and how seriously you’ve taken your education in the past.

Technical Questions

Every interview will evaluate your hard skills. For IT jobs, you’ll be asked technical questions to probe your technical skills, such as your familiarity with certain tools. You need to answer these questions in ways that clearly verbalize your technical knowledge and capabilities. 

What are the different types of technical interview questions? Common categories of technical questions pertain to your credentials, competencies, fluencies, or implementations. They can pertain to your deployment process, project management, and many other concepts.

Here are some examples of technical questions you may be asked in an interview and suggestions on how to answer them. That way you know what you can expect in a technical interview so you can impress recruiters.

How to Answer: Show that you understand the fundamentals necessary for the job by mentioning all of the languages you’ve had experience using, such as Python, C++, JavaScript, and Visual Basic. Then, identify the one that you’re most comfortable with and why you prefer it. 

What is [word]? Explain it in simple terms.

Why Hiring Managers Ask: Technical interviews will test your knowledge by presenting acronyms or terminology that you’ll need to define to prove your know-how, such as SAN, CORS, or clickjacking. They may ask you to explain it in rudimentary terms to see if you can communicate highly technical concepts to laypeople.

How to Answer: Provide a clear, straightforward definition and then describe what it’s for and how it works. The most succinctly you can answer, the better, as rambling is not often viewed as a positive trait. Also show that you can rearticulate a concept by simplifying your definition and avoiding technical jargon.

Technical Interview Tips

What is a technical interview like? Most tech interviews are highly focused on assessing the interviewee’s expertise and determining their ability to solve procedural problems. They involve a series of highly specific questions to judge the applicant’s ability to navigate complex problems, solve brainteasers, and think critically about IT challenges.

How do I prepare for a technical interview? The best ways to prepare for a technical interview are:

  • Know what the job description is asking for, including any required certifications.

  • Get familiar with the tools necessary for the role.

  • Be prepared to show your coding or programming expertise on the spot by practicing algorithms.

  • Role-play an interview with someone experienced who can test you and give feedback.

  • Make it a habit to ask clarifying questions and speak your thought process aloud.

  • Memorize as much as you can — or at least know where to look things up quickly.

  • Have an idea of how you’d answer follow-up questions to any answers you give.

Bring Your Own Questions

While it is your responsibility to prepare for interviews, and they can feel like tests, remember they go two ways. Take the opportunity to ask questions. You want to know as much as you can about a job before signing on.

Find out what tools and programs they use, what project management methodologies they use, what kind of continued education they recommend. You are also allowed to circle back to areas where you didn’t feel confident in your answers and clarify points.
