Roadtrip and BTB...come on guys, most of us hopefuls would give our right arms to be where either of you are today. Sure every company is going to have culture variations and I personally would dress in a Wimpy burger man outfit if it'd get me to the right seat. As far as advice to the originator of this thread goes, surely a smart suit and tie combo, not too loud, and neat and presentable is good enough for any interview, then it's upto him to do the rest.
