Pros
The best reason is the customers. The product Dell makes are used all over the world by billions. Being in Product Test group, I contribute directly to the quality of product Dell makes. There is tremendous opportunity and latitude in my job to make an impact and the best satisfection is if I am successful in my job, it affects positively to the quality of the product seen by billions of customers all around the world.
Cons
Being a very large company with continuous thrust on product lines bureaucracy is the biggest hurdle in Dell. Process seems to slow down itself. Also many people say Dell lacks innovation in product, although in Business process Dell's innovative ideas were unprecedented. Most employees are in Dell for more than 10 to 15 years, making the average age of employee over 35. High average employee age triggers a static environment not suitable for innovation. However, my opinion is a lot is changing in Dell, and effect should be seen in a couple of years, and people finally are getting over the transition phase to move forward.
