First day of work... kind of

So I've spent the last two days at New Hire Orientation for my job. Basically, I've learned all about safety at the office, work policies, blah blah blah... There was a lot of information and my head is still swimming. At 2 p.m. today, after getting a full tour and employee ID, I reported to my supervisor. I'd been so nervous all day about how I'd be recieved - would they throw projects at me? Would they expect me to know everything already? Would they be annoyed with my questions? Anyway, it wasn't that big of a deal after all. I was only there for a few hours, so we'll see how my first "real" day goes tomorrow.
