Pros
If you are into technology, Dell has its fingers in absolutely everything. Almost every company I have ever worked at has Dell equipment, for better or for worse. You may get a chance to work with some of the biggest names in different segments of technology.
Cons
Politics run the show. All of the executives have been there for many years, and you will have folks who will kiss their bottoms in every department. And those folks will have no problem throwing anyone and everyone under the bus for their own failings, and despite what a lot of policies and yearly ethics tests will lead you to believe, the HR department will do NOTHING about it except protect Dell from a lawsuit from you if try to bring any of it up. Almost every manager (or my manager's manager in many cases) I have had has yelled at and degraded employees in almost every meeting I have been in. If God forbid, you get on the bad side of one of them, they will make your life a living hell, and if you don't quit from it, they will find a way to force you out. The biggest joke to me is the "work-life balance." They keep bringing it up as if it means something to the whole company. It only means something if you live in Texas. Everything is on their schedule, which means 5 am calls. If you are unlucky enough to get to manage people in the US AND in a foreign country, don't expect anything except coach to fly there. I have many 16-hour coach flights under my belt to go to India a couple of times a year to meet with my group there in person. You have to be a VP to get any kind of upgrade. I was told not to expect any kind of promotion at Dell by my boss. Why? Because Dell is so big and there just isn't enough Sr. Director or VP roles available.
