Vantaggi
Super smart, kind, thoughtful people, super interesting problems, benefits of a start-up and an established company. In my experience, the media narrative just does not line up with the reality inside Uber. The people here are not "brogrammers" - they're serious software engineers that are passionate about solving a really, really hard problem. This is at the ATG Pittsburgh location, mind you, so I can't comment on SF. But here, at least, I know, it's awesome.
And by the way, the company is trying very hard to change what problems do exist in the culture. It's not just a show for the outside. Everyone takes it very seriously, and there have been incidents in which the employees took a stand as a group to hold someone accountable for actions that violated our values.
Svantaggi
Mostly: the outside image. Explaining to your friends. Having to justify to friends why you support Uber and why Uber is a good company. But if you believe that fixing a problem that causes 30,000 deaths and countless more accidents a year is important, then come work at ATG.
