Is there training provided or do they just throw you into the deep end is a good one to know. A personal favourite of mine (though not necessarily one I'd advise you asking) is 'What is the worst part of your job/what is your least favourite thing about working here?' This is a good one to ask if you're left alone with someone who is currently doing a job that is similar to the one you are applying for as if they give you an honest answer, any problems they have are likely to be ones you have too. Alternatively if you ask it while their manager is in the room (like I did) then it's just kinda funny watching their reaction as you put them on the spot with their boss there. You won't necessarily get an honest answer in that situation though. Other things I've asked about before include how much pressure is there to reach targets, are the targets achievable, how strict is the dress code, what opportunities are there for career progression, ect. The Forbes list is probably a good guide to go by. Their questions focused more on creating a good impression where as mine were more things I wanted to know. Also as an update, I have since successfully got a job. It took applying to lots and lots of jobs, four phone interviews and 4 face-to-face interviews (3 of which progressed from a phone interview). I'm also still waiting to hear back from one of those face-to-face interviews but since I took this job, I'll have to turn them down even if I get offered it.
