Pros
Free coffee! That's it, really.
Cons
They're super cheap about everything. Bring your own tissues and pens, they don't supply any. Noisy office, no privacy, no assigned seating, no personal storage. Nowhere to keep a mug, or pads, or a change of shoes. You have to carry everything home every day. Remote work for any reason is very discouraged. If your kid is sick, or you have a dentist appointment, working from home for a day counts against you, so you have to take a sick day. Dell has an official policy that remote workers may not get promoted or change jobs, no exceptions. Do you think people stay out of the office when they're sick? Zero foresight. Executives change seats, and your project gets abandoned for whatever sales emergency or buzz word project of the quarter. Upper management is all yes-men. Executives control everything waterfall style. It's all about executives getting their compensation. Everything barely works. The apps they use, the wifi, the VPN, everything is broken, frustrating, and a waste of time. Everything is cost reduced to the bone. Good college hires leave after a year or two, bad college hires stick around. Need people for a project? They're in an office overseas, they have no experience in your type of product, they're gone a year later. EMC was a great company to work for. They cared. They made great products. Dell bought EMC. Dell does not care.
