I just got a job in this industry. I start on Monday. I found it rough when I started a similar job just out of high shcool, but now that I've been out of work for a little while I'm pretty excited about getting paid a decent starting wage without having to break my back. The jobs are few and far between around here.
I don't know if your interview will be at all similar to mine, but here's what mine consisted of:
Testing
a) typing test
b) basic computer knowledge test
c) problem solving (not mathematical)
Two Seperate Interviews
Mostly questions such as:
a) what did you like most about your last job
b) " " least about your last job
c) why did you leave your last job
d) can you think of a time when you didn't follow-through with something
e) how did you remedy this situation
etc. etc.
