Traits of a bad/inexperienced interviewer

most of us have come across at least one of the following bad interviewer type:

1. Not knowing why they are asking that specific question, which skill are you testing ?

2. Those who ask questions in a Google doc. It's the worst, the candidate ends up struggling to format whatever they write.

3. Have "YouTube" knowledge instead of in-depth understanding. Imagine the candidate asking you a question and hurting your ego.

4. Asking candidates to switch on camera, while keeping theirs off.

5. Staying silent, not being interactive, not giving any kind of hints.

6. Not putting any effort to understand the candidate's mindset or background, asking intro just for the sake of it. You might work with that person, put some effort in, ok ?

7. Having a fragile ego, not accepting a different school of thought.

8. Just copying the question from somewhere & not knowing how to solve the questions themselves, giving hints which ends up confusing the candidate instead of helping.

9. Expecting the exact answer, instead of focusing on the thought process.

10. Asking Hard DSA questions in a one hour interview.

11. No proper intro, no setting the interview base, eager to just jump to questions.

12. Those who think interviews can only be for one hour, not keeping extra time. Who decided the interview will only be one hour ?

13. Not knowing how to format the interview.

Interviewing is a skill/art, please learn it, don't waste your or anyone's time. Imagine a skilled candidate not getting the job they want/deserve because you didn't know what you were doing.

It's better to treat the candidate like your other colleague and you are just brainstorming a problem.

Whenever I have come across a good interviewer, I have always ensured to tell them they are a good one.
