Amazon

High exposure to technologies. Competitive compensation and Amazon stocks (which are soaring every year). Very wide career growth opportunities (e.g., switching from technical to management/business is quite easy). Humble and very approachable leadership. Developers have great transparency in business decisions. Some very smart people to work with. Relatively easy to move to Seattle.

Very few employment incentives.

Get burdened by high operational load sometimes.

New developers often get lost because of so many internal tools.

Things move so fast that you can't afford to slack

Give more incentives to employees. They feel put down when asked what benefits they can avail at the Amazon website.

Have a dedicated team for operations as far as possible, and invest more in R&D and long-term solutions.
