Pros
They pay a competitive salary and offer great benefits. There is room to learn new technologies & techniques every day. You can enjoy lots of free snacks and drinks.
Cons
There is incessant and never-ending work, with a demand for perfection and timeliness. There is no regard for an employee’s personal time or life, and you are expected to be always on and available to work late on evenings and weekends as a matter of regular course. Managers are trained to provide weekly “feedback” which is brutal, petty, and rehash of any unsubstantiated gossip they may hear about you (so you have the opportunity to disprove it). They pay lip service to agile development - managers never say no to work and developers have to agree to any amount of work thrown at them. Everything is measured, all communications are monitored and video cameras exist everywhere, even in conference rooms. There are no private spaces.
