Pros
The Engineering and Tech Support organizations are filled with beautiful minds. There are a lot of unbelievably sharp people and almost to a person the very smartest and best among them are sublimely humble. The work is challenging but that means the workday is intellectually engaging. The people there are genuine and, on the whole, you really can bring your authentic self.
Cons
Recognition seems regrettably more like a popularity contest than anything else. Cliquishness on some teams seemed to be aided and abetted by management. Diversity is measured mostly in superficial ways (skin color, sexual orientation) and far less so in deeper ways (political or religious affiliation etc.). That said New Relic needs to do a much better job of retaining diversity.
