Understandable that these are mostly just trivia questions, my thought was that they should be a springboard (pun intended) for senior developers/managers prepping for a hiring interview, who may be a bit unsure as to what to ask.

Any candidate who answered these in one sentence/work answers with little detail would definitely not be a strong candidate, IMO. But mostly a round up of "Here's some topics to maybe dive into and get to know an engineer better with."
