Rejoining the workforce

Tuesday was my first day at Motorola.
The first thing that overwhelmed me was the sheer size of the campus. I had to go to three separate buildings that day. First, I had to go to some corporate tower to turn in my remaining tax paperwork. That took about an hour in total.
After turning in my paperwork, I was told to just head to where I'd normally work. So I did. After talking with a few people, I think HR just got rid of me as quick as they could. A few years ago, supposedly, new employees would get a full tour of the campus, including the visitors' center, a tech museum, and some other stuff. Now, it's just, "Thanks, get your badge, see ya later."
It's nice to know there's consistency among big companies. I feel comfortable being just a number right away.
Guess I'll make do looking online for benefit info and such.
After the HR excursion, I went to network monitoring. Got introduced to some of the employees and managers. Sat down with a fellow, and he advised me in the ways of network monitoring. The info is helpful, but until I get access to my own computer with proper logins, I don't think I'll really understand what they do and how they do it.
Mind you, I accepted the job offer over three weeks ago, so it's not like they didn't know I was coming. Supposedly, my computer was ready for me on Wednesday.
However, I learned from an IT fellow that my user ID hasn't extended to the whole company yet (or something), so I can't log into any applications yet. I've been told I should have access already. Hearing that, I figure I should have my computer ready by mid-July.
Side note: the job also requires a background check. So, to anyone reading this, please please please be nice to me and don't screw around if the nice folks from Homeland Security come calling. Please. I got fingerprinted. Really.
At any rate, I suppose I don't care about any inefficiencies as long as I get paid.
It's nice to get out of the house.
