Vantaggi
Work on projects at global scale. Get to sometimes use cutting edge tech. Some teams and orgs offer a lot of diversity and this job favors folks who are self-motivated. You can get a lot done if you're willing to have no life. Lot of learning opportunities to level up yourself. Pay is great.
Svantaggi
The way the teams are setup, you're ranked either in the top 50% or bottom. Raising the bar is a huge part of the game here. Instead of being happy for your teammates overworking to achieve their projects, you must be worried if you don't work on something cool as them, you can be considered least effective. The internal tooling is the worst and you'll spend most of your career debugging internal crap vs using the latest tech. So much technical debt on teams, it can be a nightmare.
