I second the thought above...I had my interview at the Borders coffee shop which was a block from my house. I live in Atlanta GA. The interview was on a Saturday afternoon. I wore a dress shirt and slacks. My interviewer - a manager from BCG, wore similar attire. The interview was informal, conversational and smooth. At no point in the interview did i get the feeling of being under-dressed.
I guess you just have to weigh the situation as it presents itself. If we were meeting at a restaurant for lunch on a weekday, I would have suited up, but w/o a tie. If i was interviewing with the AdCom or in the office of my interviewer, the tie would be on...
Just my 2 cents
I totally agree, my interview was at a coffee shop at 7:30 pm on a Sunday. I had no idea what to wear, but figured a suit would seem out of place and determining whether you can assess a situation is important. I wore a business skirt with heels and a blouse, my interviewer showed up in flip flops and cargo shorts. I was very glad at that point I didn't wear a suit, I would have felt very awkward
Seems like some of these discussions keep popping up. I would refer anyone considering what to wear to an earlier post written by an actual alumni interviewer:
