If someone shows up with a suit for an interview as an engineer, I wonder what they are trying to cover up. In terms of appearance, I expect a candidate to be clean, neatly dressed, and generally presentable. More than that starts triggering my alarms of "using dressing up to cover up capability deficiencies". I also don't want to see a poster/song/video unless its (1) academic poster or (2) they demonstrate something about your engineering prowess. E.g., I would be interested in a Youtube video demonstrating their sweet graphics/video game they wrote. In my opinion, it's all about relevance.
