what attire for an interview in Starbucks?
If you are talking about a college interview, suit and tie is way overdoing it–in my opinion, anyway. My son did not go any dressier than a polo shirt and khaki slacks, but some do dress up more than that. I think most interviewers would prefer to see students looking sufficiently groomed that they are not being disrespectful to the interviewer, but still comfortable enough to be themselves.
