Once again, didn't mention wear a suit. To the job interview I went to for my current position, I wore a nice collared shirt and tidy, neat dress pants with some well-polished shoes. It pays to look presentable, even if it is for something like McDonalds.

One job I was applying for, I wore good, clean, pants, and a nice sweater. Other guy shows up as if he just tried to emulate Eminiem.

Job was for a position as a grinder in a small factory making wood/gas stoves and inserts.

Yeah, I got that one.

I have to agree with Magnum, you need to dress somewhat fittingly for the type of work you're being interviewed for. My friend showed up to a welding interview in dress pants, dress shirt, etc: They turned around, sat him at a welder, and told him to show them how well he welds. Ruined his clothes, but he got the job.
