Should I shave it?

I have been working on a respectable goatee and I like it a lot so far. The problem is this: I have a job interview at a marketing firm on Wednesday morning and I don't know if I should just trim it so it looks like it has a purpose or if I should shave it off and admit that it has no purpose.

The attire required for the interview is business professional, so I am thinking that shaving it off would make the most sense.

Tell me what you think...
