Pros
As a developer, you get to work on very interesting products using cutting edge technology. 3 weeks vacation to start + they give a week off at Christmas (not guaranteed, but they have always done it since I have been there). Rarely a problem when requesting time off either. They understand people need a break and don't run people into the ground. The work environment is great: Fully equipped gym, foosball and pool table, PS3 with a bunch of games, free coffee, no cubicles (except for tech support). They will help pay for work-related training (including university) and also offer employee referral bonuses.
Cons
Can be a bit difficult to advance if you are looking for the fast track to a management position. Company is transitioning from small to medium size and it no longer has that tight-knit family feel to it.
