I had someone come in for an interview one time wearing denim shorts, dirty tee (looked dirty to me anyways), and a bandana on his head - and to top it all off, he kept responding to text messages during the interview, and when he wasn't texting, he had his chin in his hand, leaning on the table like he wanted to fall asleep. When the ETL doing the 2nd asked me my opinion, I didn't even want to give an answer, but I gave a "brand" response, and then after he did the 2nd, he pulled me aside and told me, "that's why you had that look on your face when you answered what was he like." We were both in utter disbelief at how some people act and dress during interviews
