Essential IT Interview Questions and How to Answer Them

Getting the jitters before an important IT job interview is only natural. The mind is racing with thoughts like, “Am I prepared enough?”, “Have I brushed up on my skills and knowledge?”, “What if they ask me something I don’t know?”, and so on.

Take a deep breath and relax. We have you covered. This article explores the most common IT questions that get asked in job interviews, including tough and technical interview questions, and how to answer them. Let’s jump right in.

Before the IT Interview

Don’t go unprepared for your IT job interview. Not just in terms of brushing up your own skills, technical knowledge, and experience but also in knowing about the company to which you have applied. Preparing for IT interview questions involves researching the company, understanding its vision and goals, and being able to articulate how your skills and expertise are aligned to meet those goals.

Before we take up each question and answer here is a quick look at the three main types of IT interview questions.   

Types of IT Questions

The three most common categories of questions generally asked in an IT interview are:

• Personal questions: To assess your work style and abilities.
• Job and company-related questions: To gauge if you are a good fit for the company.
• Technical questions: To learn about your knowledge, problem-solving capabilities, and on-job expertise

Now, let’s move on to some common IT questions with answers to help you make a lasting impression on the interviewer and elbow out the competition. Interviewers usually start with the basics and then build up to the more difficult questions, depending on the position for which you have applied. Here are the top IT interview questions you need to prepare for:

1. What is an IP Address?

At first glance, this seems like such a basic question. Internal Protocol (IP) address is something every IT professional is aware of. However, the interviewer is not looking for a textbook definition. They are keenly observing your practical knowledge and communication skills. Elaborate on the question and give a detailed explanation to display your skills and knowledge with this seemingly easy question. 

Of course, this is simply an example of how basic IT interview questions cannot be ruled out. A plethora of basic questions can come your way, so be prepared for anything and everything. 

2. How do you approach an issue when you can’t solve it?

All IT professionals have encountered situations where an issue seemed almost impossible to solve till they finally solved it. It calls for essential traits like patience, perseverance, and consistency. Faced with such a question, you need to answer honestly without exaggerating. Highlight how the qualities mentioned above helped you solve the problem effectively.

3. Have you ever taken the lead on a project? Tell us about it

This is one of the most common IT interview questions as recruiters want to assess the leadership potential and team spirit in a candidate. Since the IT industry thrives on teamwork and collaboration, possessing leadership skills is a great point in your favor. Emphasize how well you work well in teams and give examples of your proactive approach.

4. How do you stay up to date about new technology?

This is the perfect time to showcase your industry certifications and any courses that you may have taken. Since the IT industry is a very dynamic one, staying updated with the latest trends and technologies is an absolute must. The answer to this question reveals how aware you are of the new developments in the industry and also your keenness to learn and grow.

5. How familiar are you with the different operating systems?

Different operating systems are used by different companies, such as Windows, Mac, or Linux. So, if you are familiar (and have expertise in) with the OS used by that company, that’s a big plus in your favor. Ideally, being familiar with all three is what the interviewer is looking for, so showcase your versatility and quick learning skills. Talk about the operating systems you have worked with, and throw in some problem-solving instances (if applicable).

6. How would you make sure a computer network is secure?

This is probably the one question that could tip the scales in your favor. The recruiter wishes to know how knowledgeable you are when it comes to keeping their data safe and secure. To reassure them that you are the right fit for the job, tell them all about basic security features like firewalls, routers, VPN, and others to demonstrate your expertise with them to ensure the safety and security of their company’s data. Again, this could be a good opportunity to share a real-life example of when you may have encountered a security breach and how you solved the issue successfully.

7. Why did you decide to go into IT?

Another commonly asked IT interview question. Be honest and tell them why you decided to pursue a career in the IT field. This helps the interviewer gauge your passion and commitment for the work at hand.

8. What made you apply for this position?

If you have done your homework regarding the company beforehand, this should be an easy question to answer. The recruiter wants to understand your roadmap, your growth plans, and expectations from the company. This is also a tricky question because your answer will be assessed carefully to see if it aligns with the company’s own goals and vision and whether you are a good fit for the company or not.

9. Why should we hire you?

This one is almost similar to the one above but with a slight difference. The recruiter wants to assess how good a fit you are based on your strengths and capabilities and the passion and dedication with which you answer this question.
