my interviewers were mostly mid-age, i.e. around my age, and we had pretty nice time, relatively easy questions/exercises, talked stuff about current and future products/techs, etc. - overall pretty typical interview, and i kind of was surprised what all the talk about their interviews was about. (too bad the offer was a very low comp L5 - that left me traumatized :). I guess you get what you pay for - i.e. i suppose one should pass their signature tough interview with the young hot-shots to get a good offer :)
