Pros
What you can accomplish here is basically limited only by *you*. If you see something that needs doing, it's not *that* hard to sell it and get started. There's a lot of freedom here. At the same time, if you're a junior person looking to learn stuff, there are great mentors here. If you're technical, don't be put off by the idea that this is a storage outfit; there are all kinds of interesting things to work on here. Great communication from upper management. I used to work at a place where you'd read something about your company in the paper before you'd hear it from The Boss; here, they trust you not to share information with 200 of your closest friends in the securities industry. And speaking of the boss, our chairman/CEO and the president/COO are outstanding guys. You know that they're interested in the company's future and not in this just to get rich themselves (Dan would have quit a long time ago if that were the case). They are here to create an enduring organization that will contribute to the industry long-term, and thus have no problem telling the stock analysts, "We're gonna invest in the company's future, rather than doing artificial stuff to make you guys happy this quarter." I love it when execs at a public company this size can say that -- and do!
Cons
As someone else has noted, we're trying to grow into the size we've become. Though the small-company feel is great, it comes at the price of some immaturity in the area of "processes." So we've got to work on that. A lot of your experience at NetApp (as anywhere) depends on who your direct supervisor is; get assigned to a bad one and things will not be so happy.
