Pros
There are some amazing and very smart people working here, people you can easily get along with and want to be friends with. The company's name definitely carries prestige and it opens up many opportunities.
Cons
The pay is lower than what you will find at other similar companies and so are the bonuses. They are very cheap, nothing is free in the office, the cafeteria is outrageously overpriced, and they make it extremely difficult - borderline impossible - to expense or reimburse anything. The upper management refuses to look in the mirror and doubles down on poor decisions (i.e. refusing to address low headcount) that trickle down to the people doing most of the actual work that keeps the company going. They've built a name and reputation but if this keeps going on, it will take a hit too.
