I haven't really posted a lot here, nor do I come here often but I thought you might find my experience interesting (I find it hilarious).
I recently interviewed with a reputable PE shop. Now because I'm currently with an IB, we agreed I would drop by during luch and have an _informal_ chat with the HR. That was supposed to the screening process. I was fine with the why's and how's but I kind of felt that I was failing to establish rapport with the lady.
Anyhow, 4 days later I got my feedback: ding because 1) I was not wearing a tie and 2) I was not wearing a suit!!! Gosh, that was the most hilarious (I would refrain from using other adjectives) thing I had ever heard. Granted I was not wearing a tie (not a required piece of attire at the bank, at least not if you're a mere analyst) but to say I was not wearing a suit is ... uhm... show shall I put it... to stretch the truth!
I wonder if it is some new type of rejection letter, PE-style :-D
