Typically at the end of an interview the interviewer will ask you if you have any questions. Instead of bumbling through awkward, potentially inappropriate questions, keep a few good interview questions handy.
1. What made you choose a career with [COMPANY NAME]?
People love talking about themselves. Your interviewer will probably not be above this inclination. This question shows that you have an interest in both the job and the interviewer.
2. What type of informal mentorship opportunities does [COMPANY NAME] have?
Your office will be a classroom. Very rarely does academia prepare you for the work you'll be doing in the office. While the company website may talking about formal training and mentorship, informal mentorship is very important.
3. What kind of expectations does [COMPANY NAME] have for new [POSITION]s?
The answer to this question will give you information about what you'll be doing in your new position and send the interviewer the message that your head is in the right place.
