Pros

My experience has been extremely positive but speaking only within my team. The company is large and I’m sure there is an array of experiences possible based on your team. The company seems to be proactive in some regards on employee satisfaction.

Cons

I don’t have many qualms with the company at this point. The company seems to be well ran.
