Pros
Very interesting work, more so than industry. Reputation is everything. Once you establish a good reputation work will find you ( because management isn't responsible for finding you work) and you will be given allot of creative freedom. Since you find your own work you tend to work with people you like. People are friendly and helpful.
Cons
Terrible location, horrendous traffic. Having to find your own project work. Most dysfunctional company I ever worked for. Cramped work environment. Being friendly and personable is valued more than competence. Can be very slow at times. New CEO has made some long overdue changes but he is destroying Draper Culture and work environment. Existing management too spineless to say anything ( classic case of Peter Principal). If you really want to work at a lab in the Boston are, try Lincoln instead.
