I was recently referred by one of my buddies to his boss for a job on a computer repair tech bench. It is for a national chain which realy hate.. but that is besides the point. (best buy).

The job would include simple stuff like setting up a new PC to make sure it works, installing service packs and patches, turning on auto update, tweaking the system for performance, installing software, removing spyware/viruses, resolving system errors, etc. All easy stuff. Basically... any service that you can go into best buy and have done to your PC.

I know I won't have a problem doing anything on their list.
I do it all for my own systems and all the systems at my full time job.

I sent them my resume and they really wanted me to come in for an interview.

This is only going to be a part time summer job to make some spare $$ to buy my honey a nice engagement ring. I could put it on credit or get a loan... but I'd rather pay for as much of it with cash as I can.

This is more of a questions for those who have worked for or interviewed for a type of position like this. What should I do (if anything) to prepare for the interview? Is there anything specific I should study or be ready to answer?

I know they are going to ask me tech related questions which I beleive I'll have no problem answering. I've been eating/breathing and sleeping technology for the last 5 years full time. I've been playing with computers as a hobby for the past 10 years.
