Ditto seeing as we're here to discuss the practices of running startups, among other things
Anyway, I'm sure the realities of working for a BigCo will continue to sink in as time goes on (if you think Facebook is still a startup, keep drinking the koolaid). Congrats on the sale to Facebook, I hope the next few years on the earn out are good for you.
EDIT: I notice you added the comment about the glassdoor link... it's not about appeasing me, it's your team and your employer, do what you like. But I would comment that while the interview Q's are out there, if someone was going to walk into my interview office with them already in their head, I'd like to think it is because they were savvy enough to go find them on their own and not because my staff member pointed the candidate directly to them. Just saying.
