Pros
High pressure atmosphere where you will learn a lot in a very small amount of time. If you can stick it out, a few years will look great on a resume. A great entry level 'stepping stone' IT position.
Cons
Sales motivated technical support. As technical support (web advisor), they force you to 'helpfully' recommend products and put a great deal of passive aggressive weight on making sales. A lot of the products are broken in ways that make you feel like you are scamming the customer. There aren't enough products that will actually help the customer so you'll end up cheating yourself an honest day's pay all of the time to get ahead. If you want to see for yourself how desperate it really is, open a live chat with technical support. Coaches are not technically trained so don't expect to be able to go to a coach for technical advice.
