As an addendum, when I'm the interviewee, and some joker interviewing me is wearing scruffy clothes, it makes me less likely to want the job; I'm not asking for the interviewer to be wearing a suit, but jeans frayed at the cuffs and a faded t-shirt? I'm sorry, have I accidentally wandered into a job interview for flipping burgers? Sure, it's one factor amongst many, but if the interviewer can't be bothered to try to present at least a smart appearance, it makes me wonder what else is going wrong in the company; do they want to hire good people or not? Ironically, these people are often found to heavily support the idea of beautiful interfaces and advocate how important appearance is in UI and so forth; well, a conversation with a person is very much a UI for getting a job.
