That seems crazy to me! Whenever I conduct interviews questions about specific situations from their past experience are most of what I ask. "Tell me about a time when..."
I find they can very quickly uncover potential red flags. They can also lead to interesting discussions that leave both me and the candidate enthused about progressing to the next stage.
Literally! I can count on one hand the number of interviewers who have asked me about my past work experience. The most important thing seems to be whether I can regurgitate various tree operations on a whiteboard. It's only a matter of time before they cut out the middle man and start hiring candidates by (university_ranking, hackerrank_ranking) in lexical order without as much as an interview.
