Pros
Good pay. Great learning opportunities. Unique problems to tackle. Scale at altogether different level. Fast paced environment, It's a crash course of whichever stream one is in.
Cons
Very stressful environment. If your manager/leadership isn't supportive then your growth is stagnated. It's kind of a heartless company and nothing can come in front of targets and metrics to meet. But it all dep nds upon the team one is in, there are many great teams as well. It's "promotion driven development" environment and people work on and or even choose projects which would help them get promoted. People will interact with you after having a look at your "level" and you may not get a response quickly if your level is lesser than the other party. It's not everybody's cup of tea.
