Avantages
The salary is pretty high, all-in-all I was at about 160k/year. Still not worth it.
Inconvénients
The culture is awful, if you're a software engineer I highly suggest you find another job as there are many more. I worked in downtown Seattle for an AWS team, and everyone in the building I worked in seemed perpetually depressed. Hours were long (some team members worked 30+ hours straight), and almost all employees were foreigners on H1B visas who were more-or-less forced to put up with the conditions or leave the country. In addition to this, the internal tooling is really old and outdated, leaving few opportunities to learn cutting edge technologies and the developer operations is an extremely mismanaged nightmare. I've never seen people crying at their desk like some claim to have seen, but nonetheless, this is obviously not a healthy place to work.
