Pros
Dell Computer is a large company, and because of that, they have a large number of resources to work with. I worked as a local campus representative, and I found that I was paid well and given plenty of incentives to keep working. Good work also received great recognition from within the company. At one point I was even telephoned by one of the VPs at Dell in Texas. I had three managers while working for Dell, and I have to say that to this day they are still the best managers I've ever worked with. All were motivated sales guys who had a lot to show for their hard work. So all in all, if you land the right spot with the right managers, you will get the resources you need, the incentives you want, and hopefully some great guidance.
Cons
The downsides of working at Dell really depends on your career path. As a local campus rep I did not encounter many downsides, except for some irregular hours. For sales position within Dell they did require you to work in Texas at the ground level for a minimum amount of time. I noticed that this requirement was not met by many sales guys who got in before this "idea" came about. By ground level I mean answering telephones and helping customers or clients. Being asked to work a job that doesn't actually require a college education is a bit of a disappointment.
