Pros
Good: The benefits are really great (401 K is one of the best in class), Health insurance is OK. flexibility in working from different locations within and outside the company. Very informal and relaxed work culture. People are very talented and are helpful.
Cons
Cons: No work-life balance for some groups (M&A, CM) with too much work and no work in others (ops). Lot of good work was been scrapped on the whims of middle management. Middle management: (Directors, sr. directors) are incompetent bunch and are more in numbers than required. Many are very talened but have no people management skills. Performance reviews should be more transparent but ends up being a blame game to pass Project lead's and sponsors' incompetence to the team members.
