When I worked at Best Buy many a years ago, Geek Squad isn't that bad of a job. If your just an in store agent, 75% of your job is going to be New PC Setups, which will consist of the normal startup garbage and installing Security packages (Granted the Salesman landed the Security Package). Aside from that you will deal with people bringing in Computers to get fixed. You will need to convince these people that the $149.99 your going to charge for JUST a diagnostic, is worth his 300 dollar Dell or Emachines computer. At any rate, Prepare yourself to get yelled at by customers because of what GS charges, Lmao. In terms of how good Geek Squad is, They're not the greatest techs out there, but it pays the bills I suppose.
It was an After highschool Job, Which for the most part I can't complain about it as I was on the Comp Sales floor. The atmosphere I found quite pleasing while working there.
Not sure how much it's changed since I've been there, Which is quite a few years.
