To tell you the truth, I think that the Shaved look is alot more accepted in an interview than anything else. I mean, if you take the care of grooming yourself well, go into a interview clean shaven, shoes polished and looking solid all around, You are going to put off that Clean Look. I don't care who you are interviewing with, the worst thing in an interview is if you do not look Kempt. the Cleaner the Look, the more points you score.
My Father was a Exec for most his life, his resume does have VP for Levi's on their so the advice he gave me is definitly not Bull. He always told me two things would make or break the Look: Teeth and Shoes. As he said "You always take care of the large things, the suit the Tie, Etc... But its the small things, such as if the teeth are white & the Shoes are Mirrior finish that shoes attention to detail, no matter how large or how small."
