Avantages
Big company, so a lot of different kinds of experience is possible. Lateral movement is possible across groups. The company gives you decent benefits. The salary is average in the industry. However employees get a very good exposure, something which is very important atleast at the beginning of your career. You can switch careers as it is a big company and there are different opportunities.
Inconvénients
However the company policies and management structure makes you do dependable on one person, that is your manager. They have not implemented matrix management or cross management structure, which makes an employee very vulnerable to the whims of the managerial hierarchy. They take away your normal holidays even for genuine medical leave (atleast most managers do that), which is something they can improve on. Specially if you are an international working on H1B, you need more than a few days a year to travel to your home country.
