What reservations or considerations do you have about working for this company?

This is not a trap question, but is rather an opportunity for you to get a few of your questions answered by the interviewer.

There is only one correct response on your part ..

Your response MUST be: "None !! I am anxious to get started .. when will I know if I have the job?"

Note: if you have any actual reservations about working for this company, keep them to yourself, the interview is not the place to express your reservations. And, if you get a job offer from them, you can always turn it down later.

This response should also give you ample opportunities for follow up questions like "may I have your email if I think of any followup questions?". Or if you have developed good rapport "how do you like working here?"
