I specifically bought a banded collar shirt for interviews, because you can't wear a tie with one
My hiring experience conflicts directly with this statement. As in, hired a guy that came to his interviews in a suit/tie, but ultimately had low levels of professionalism and common sense. My absolute best hires have been people that showed up in a dressy shirt and sometimes a tie.
The fact that we're having this discussion means that it is NOT common sense.
Common sense = just took this food out of the oven, of course it's hot
Wearing a suit and tie because... some people think you HAVE to wear a suit and tie? Not common sense. Actually, it runs counter to common sense IMO, in that there's not a valid, logical reason for it, and there isn't a universal constant for it.
