Like it or not, people make assumptions about a 6 inch beard. You listen to metal, you like snakes, you have smoked the marijuana plant like a cigarette at some point or another, you may have been in a fight at some point, you have a dislike for authority, you play World of Warcraft, you wake up at noon on weekends, and the list goes on and on. Your goal at an interview is to make people see you differently from that. Once you get the job, you show your abilities and earn respect and THEN you can have a beard because you're past the initial judgement stage. If my boss saw my huge tattoos at my interview I wouldn't have gotten the job. Now he makes all kinds of jokes about how I look like George Clooney in Dusk Till Dawn - because he knows I am a hard worker and take pride in what I do and don't let my personal interests affect my work.
