Do you have any questions that I can answer?

"I am supercurious about the story of the post-it, and how it relates to the 15% culture at 3M. What department was that employee working in when they invented it? How did it come about, and what kind of inventive stuff are 3M employees in the varying departments and positions encouraged to do?"

As 3M's recruiters advise, "If you don't understand a question, go ahead and ask for clarification. Be sure to come prepared with a list of questions for the interviewers as well. If you don't get a chance to get all your questions answered, make sure you know who to follow up with before ending the interview (either the recruiter or hiring manager). A good way to close an interview is to thank the interviewer for his or her time, confirm your continued interest and ask what you might expect for next steps and related timing. Of course, a follow-up thank you note is never a bad idea!"
