I've interviewed people a bit. While I might wear jeans and t-shirts to work, if an interviewee does not have the decency to dress smartly (maybe not a suit, but at least business casual) for an interview, here is the question that would come to mind. If this job isn't important enough to this person to at least look professional, how important is it going to be after the person starts? So dress smartly. Most companies I've been to let you know that they don't require suits if that is the case, but don't go below business casual. As for cover letters, throw out the template. Every job is different and there has to be a reason you're interested. Right that down and do it honestly. If you feel you have to just cause you have to, chances are that it isn't worth it.
