I'm assuming the answer is yes...but I found it to be a unorthodox situation:
I was interviewing for a summer internship position with 4 people a company (not including the hiring manager) for 30 minutes each. Another candidate (a classmate of mine from my Masters program) was interviewing with the same people, in a staggered rotation around their offices with me.
After we finished meeting with these people, the hiring manager (an alumnus of my Masters program) brought us in [b]together[/b] to finish the day with an interview with her. I was intending on closing here, but I was thrown off by having the other candidate in the room.
I'm fairly good friends with this particular classmate, so I didn't really want to embarass her by closing in front of her. Additionally I didn't want her to reiterate my close as her own, eliminating my MT advantage =)
I'm planning on closing in my follow up thank-you notes, phone calls, emails, etc.
Would you close in that situation? I feel that I probably will if it ever happens again...which I doubt.
