Pros: You see direct impact in your work everyday. You get to actually feel like you are changing the world and see it everyday. You work with the brightest minds and get to learn from them non-stop.

Cons: With a large mission and large vision comes large responsibilities. You must learn to prioritize quickly and be self-sufficient in your work.

Pros: Good pay, meaningful projects, and plenty of autonomy.

Cons: Long, long hours, immaturity, and fighting with teams for every small decision.

Pros: Benefits, free food, and looks prestigious... unless you work there. Then you know.

Cons: Toxic work environment and people, long unpredictable hours, relatively low pay, corruption, extreme narcissism especially from people who have been there longest and have no formal education. Your reviews are based on co-workers' opinions of you and not facts. Lots of insecure people threatened by new ideas. Worst mistake of my career!
