Pros
Excellent products to be working on. Excellent tools available for testing. Ridiculously talented individual contributors to work with. Cafeteria has decent food at a decent price. Great perks with occasional beer bashes and film screenings
Kontras
Tiresomely long hours. Short deadlines bordering on instant burnout. Impossible to make weekend plans as weekend work is routinely demanded on extremely short notice. The aforementioned perks are first come, first serve, and chances are you will not be able to take advantage anyway, because of last-minute, emergency testing that needs to be performed. Management will make you feel guilty about taking your family vacation. Management will make you apologize for your child's medical emergency pulling you out of work. Management will gladly work from home, yet scoff at the idea that you can attend a doctor's appointment mid day.
