Pros: Fast-moving, great culture, hard-working and supportive team and leaders. Great place to start your career.

Cons: There's a lot of pressure to release new features quickly, which leads to a hectic work schedule and huge operational overhead.

Pros: Good tech stack. Lots to learn if you can survive, although it's doubtful.

Cons: Extreme work conditions. Extremely tight deadlines. You are expected to deliver two weeks of work in one week. You are expected to work 15+ hours and deliver, along with weekends. No regard and respect for employees. Not sustainable at all for anyone sane. You will be over-burdened with work most of the time. No concept of work-life balance. Overpopulated place. Nobody has time to chit-chat. Grilling machine. If you're not overworked, you're a waste of resource. Working on weekends is the norm at Amazon.

Pros: Money, fast-paced learning environment.

Cons: The culture is not very good.
