Asking the right question in an interview

Here's an interesting discussion on slashdot on what questions to ask a prospective employer in an interview.

Netkraft had interviewed me in my sixth sem of Engineering; there was a full year to go before I could join the company. In that interview, I remember asking "Assuming that you do select me in this interview, what technologies should I study over the next year to prepare myself?" Seemed a little overambitous to me at first, but I got the impresseion that the interviewer might appreciate a little brashness ;-)
