Honestly, I don't like the advice people are giving to just dress "how you would every day" because that's the real you,etc... The bottom line is, when you are programming all day and only meeting with maybe an internal manager / team leader, etc there is little reason to dress up. However, I would think if one day you have to sit in on a meeting with an important prospective client, you might dress a little differently than you do normally when you are just doing programming. Business people often dress up because they have meetings and it shows respect to those they meet with, I can often tell around my office when a "business person" has a day with no important meetings as they tend to dress down those days. When you go to an interview, you want to show the person respect and it is a special situation, its not just another day at work. You aren't part of the company yet so I don't know why you should have to wear exactly what you would when you actually start the job. I don't wear a tie, or a suit, but I do tend to dress up a bit. If you don't want to, thats fine, but there's no reason to deride someone for thinking they should treat an interview a little differently than they would just another day at work.
