This is insane to read. You don't get brownie points for what you're wearing, but deducting points for someone trying to impress folks by dressing more formally than what you're typically used to?
Yes. I deduct points for people who can't into social cues and context. Such is life, we are social animals. I'd deduct points if a candidate showed up in beach shorts too. (A suit is as wildly inappropriate in this context as beach shorts.)
