What are the first three things you would do on your first day working here?
Sigiloso
If I were the interviewer, I would nitpick that one of the first things you would do is go home. It's a good answer, but you want to just scope out the books. Don't take them home until later when your shift is over. (For this particular position I would be watching closely for the precision of your use of language and this would stick out to me.)
