Pros
First off, AppDynamics is composed of some of the nicest, most talented folks I've ever worked with. Cisco benefits are great and the company mostly embraces a thoughtful strategy to how they treat employees. There is some kick-ass talent amongst the fold here, and I learned a lot.
Cons
Sadly, AppDyanmics has in many ways been in decline since the Cisco acquisition, with a tumultuous amount of attrition due to a careless approach to the company vision, Cisco integration, and the processes to support the necessary (fast) evolution to SaaS software. I witnessed countless well-intentioned projects sink or crumble under the weight of mismatched expectations, lack of support and/or project leaders leaving midway through execution. This was a serious problem at AppD that I hope they take equally seriously in their approach to fixing it.
