Maybe I’m an outlier, but I actually like the unwritten rules better than the written ones. Every interview I’ve ever had I make a point to ask what would be expected. At my MBA program (yes, I’m one of those guys) we had to wear slacks and a button down to class every day. And having worked for NYC firms there are different social expectations. So my question is usually phrased like this: “Hey, I’ve worked in situations where a tie was required and where a tie would get one ostracized. Can you give me a quick heads up on normal office attire?”

This usual ends up with some decent back and forth and inevitably I send them the following Oatmeal comic. [0]

My point is that if you play it right, you can turn awkward social norms to your advantage. You just have to be willing to ask.
