Why do some of you insist on a suit and not on a tux? Black tie or white tie for my junior account manager interview?
In this day and age, even Mary Kay saleswomen have their own websites. If you go to the company website and cannot find a single person in a suit, you should be able to figure out the culture. If you're interviewing at Ernst & Young, you better get your three-piece on.
Because a tux is considered formal wear. A suit is considered business wear.
I don't think it's that difficult to understand. I actually don't care if an HR person is OK with a person wearing shorts to a job interview. The problem I have is that it's not common knowledge. You may be the perfect skill set, but your suit kept you from getting the job. I hate when people change rules, but choose to keep it to themselves.
