As in interviewee, I hate 'tricksy' questions, intended to be revealing. They just make accomplished liars and bullshitters look good.
Many excellent candidates will be thrown by them and freeze or gabble, which then throws them off balance for the rest of the interview, so they cannot show you the best of themselves.
Interviews are a uniquely weird, stressful situation. I don't buy the line that they're no different from a presentation, or high pressure meeting once in a a role. I've done all of those and they're not.
The potential employers I have respected the most have been those that respected their interviewees and tried to put them at ease. That is, I have respected them because of that but more so, there has been a close correlation between their behaviour at interview stage and as employers.
I realise that 'revealing' doesn't necessary mean tricksy but often it does. Just ask normal questions, related to the role and competency description you provided in the application pack, listen to what people say and follow up conversationally, if relevant. IMO good interviews are based on good rapport. Don't blow that but trying too hard to be 'clever'.
