Anyone here use it? i mean for work?

I just applied on a opening that ask me to be proficient in Access (intermediate knowledge of it). I said i was but I'm more of a noob at it. I'll try to take a course in it if ever i get to the interview stage of the job.

But just how complicated is this software? I'm a very fast learner... I don't think I'll have any problems to at least look like i have the necessary skills. But you think a couple of weeks of work would be enough to actually use Access at a intermediate level?
