If you have a good SPE this job is so damn easy.
I do wonder what art units most of you who have trouble are in.
Sounds like you are in one of those easy art units, such as that deals with toiletry.
I'm in a fairly tough art unit, and I've also had a fairly easy time with it. Got promoted to GS11 within a year, never had to work voluntary overtime. I think it all just depends on your training and your SPE.
Is that done before I start or afterward? Is there a chance that I might have a problem given that I don't have any criminal record or anything like that.
Dude, don't stress out about it. Follow the directions they give you, and you'll be fine. You can have the fingerprinting done at your local police station beforehand for a nominal fee.
