Some good things, some frustrations
Pros
Work/life balance, collaborative culture, volunteer-time-off policy. I've had opportunities to work in different technology areas--product code, quality, developer tools. The initiatives around quality have made it easier to find bugs sooner and back them out of the code base; we are on a good trajectory in this area. I have great relationships with my colleagues and the first few levels of my management chain.
Cons
Life as a Data ONTAP developer has its frustrations, starting with access to the engineering environment (via the vmware horizon client) and erratic build farm performance; these make it hard to be as productive as we'd like to be. Some programs were killed several years (and million$/billion$) too late, and some acquisitions should never have been made; it's frustrating to see all this waste and to be told there's not enough money to make this or that improvement for developers.
