Recently I have been a part of a few interviews and have had to prepare some IT interview questions for candidates. I thought I would post them here for future use and in case anyone wants to use them. I’m not posting answers for the questions. My method is to let the answer for a question lead to the next one, so it’s not really whether the answer was technically right, but how the question was answered.

For example: when I ask “Name three different virtualization hypervisors” you could answer the question precisely. After a precise answer I might ask, which is your favorite and why? If you answer the question “Name three different virtualization hypervisors” with a 10 minute story, I know to only ask one or no more questions if I want this interview to end soon.

The following are technical interview questions that I use. I may add more as as time goes on because technology is always changing. (Updated 9/13/2023)

Technical Questions

  1. What is the difference between virtual desktop and remote desktop?
  2. What is a hypervisor? What is a bare-metal server? Give some examples of operating systems for each.

The next few questions are more generic and are meant to get the know the person. Anywhere there is ‘IT’, that could be replaced with your job department and the question would still apply.

Generic Interview Questions

  1. What are you doing to stay fresh and grow in IT?
  2. How do you work from home in IT? What is your day to day like?
  3. How do you deal with conflict when you do not agree with the IT business decision that is made by management?
  4. Why are you looking for a new position or leaving your current position?

  6. In a fast paced, non-stop position, how will you deal with the demanding workload after 6 months?
  7. Tell me about the most interesting project you have worked on this year and the biggest thing you learned from it. 
  8. What is your greatest personal accomplishment?
  9. What is the question we should have asked you? So, what item should we know about you or parting fact do you want to leave us with? 

Hope these IT interview questions are helpful for anyone who needs some added questions or wants to prepare.
