I had a mohawk for years...my HR rep assured me it was fine. He said I could keep it under my hat nbd. I showed up at integrad rockin it like always nbd was pulled into the managers office the second day, bright and early. She explained that she had to contact corporate HQ to ask for clarification and they were crystal clear on the rules: shave it or back to the hub. I told her no problem, packed clippers with me jic. I called my HR guy and let him know, shaved my head, crushed my tests, passed the course went back to center and was put on a killer training route and just made book. Lol. Lucky me. Anyway, in my experience they're serious about everything, you have to prove you'll do anything for the job. Even have to write them a letter explaining why you believe you deserve the job and why they should choose you.
