Pros
People are mostly good-natured and fun. They like them some technology. Nice facilities. Lax dress code. Work from home allowed. Many long-timers. MBA club - Does not make it easy. MBA managers have higher expectations. Great place for women, not so much for men. They go overboard on the PC and fairness crap to the detriment of non-preferred classes. Compensation decent - once in, they will claim to be restricted to low percentage adjustments so negotiate for max before hire. Ask for the salary range for the job. Ensure you are in the correct band - Developing, Proficient, Expert. At least ask for median. Job ID can determine bonus amount. If code is 40123, code 50123 has 2x bonus and salary range. The 5 job may not be available, but ask about promotion.
Cons
Regular reorganizations. No dedicated office space. Open floor plan/noisy. Loyalty to owners/stock price bring annual layoffs - Merry Christmas. Love outsourcing - can make for 1am conference calls and 20+ hour days. Shrinking customer base. Do not see as a growing business. Terror activity can have large, immediate impact to business. MBA club - creates a class culture. Perception of veiled hostility toward men.
