The interview is a 2 way street. While the company makes you jump through hoops to see if your good enough, you also have a opportunity to determine if you want to work for them.
I like to ask "what will I be working on in the next 6 months" that way you don't rock up and than the second day they through you in the deep end of building a iPhone app.
Granted, startups only have a vague idea of what they will be programming with short periods but it helps.
Also ask "what will be my performance indicators". If they don't include "being able to very quickly learn new technologies" its hardly your fault.
