Pros
The only positive to working here is that it is experience you can put on a resume. Though the skills you learn are not readily transferrable (depending on the department you work in), it does expose you to a technical field if that is what you are looking to get in to. I worked in the Apple department, and since all of Apple's repairs are done in depots similar to this one you are unlikely to repair an Apple product outside of one.
Cons
I'm writing from the perspective of an Apple Repair Tech and all my feedback is representative of a person in that position. The biggest drawback for this job is the compensation. I was originally hired on as hourly for a reasonable rate. About a month into my employment everyone was switched to piece-rate (meaning you get paid per unit you repair). In my opinion the pay per unit was insulting and I only continued working there until I found a better job. Management continues to tack on more and more administrative duties to the techs that have nothing to do with repairing computers and pay nothing for it. At the end of the day the excessive amount of non-computer related work impedes good technicians from doing the job they were hired to do.
