Ask HN: What makes a technical interview crappy?

What makes a technical interview crappy? An insensitive asshole who makes it his/her mission to make the candidate feel inadequate by asking trivia questions.

A mature interviewer holds the hand of the interviewee and makes them feel respected and appreciated. A good interviewer moves on from the topics if a candidate is struggling and wont embarrass them.

It may sound like simple advice, but preparedness. Know who is interviewing, when, what everyone is covering, and how long it will be. The worst interviews lack of communication and coordination. The actual interview doesn't matter that much, as the culture is most likely already defined, so just test and question what you hold as important as a company.

If you was an interviewer then avoid asking PhD-grade questions (that are not relevant to day to day activities). In the end it all boils down to proper motivation, with no motivation even a professor won't contribute much to your business.

Are you the interviewer or the candidate.
