Pros: A lot of reviews on Glassdoor are from Drivers/Partners that don't capture how the engineering culture is. Company is solving a really big & tough problem: ground transportation. There is a whole new level of reliability that is needed for Uber's systems, due to the fact that it is moving real people and things. Facebook/Twitter/... not loading for 20 minutes is bad for the company's business. But Uber not working for 20 minutes means someone misses their interview, or someone might be stranded for a while. So, the company seems to be ready to invest in a lot of long-term technology pieces needed to get there. If you are a developer hungry for working & experimenting with new software systems, I would say Uber should rank among the top 3 places right now in the Valley. People are nice and generally willing to help you out. Everyone is tuned (the onboarding process is very good at tuning new people also towards this) to working towards getting things out of the way and marching towards the company's goals. So, if you believe in the vision of Uber and have an attitude of making progress, you will do absolutely fine here!

Cons: As with any high-growth company, not everything is necessarily figured out. There is lots and lots and lots of work to do, which could mean longer working hours.

Pros: A fast-moving, risk-taking engineering culture where we work hard but are constantly rewarded by experiencing the success of our efforts. The level of intelligence and the level of fun on our team amazes me every day.

Cons: Intensity, autonomy, winning ideas that come from anyone in the company regardless of seniority or tenure... Ingredients that make us successful, but certainly not for everyone.

Pros: Working at Uber has been awesome. It's a fast-paced environment where you're always on your toes to learn new things and implement the latest tech. There's so much going on behind the scenes at Uber that your opportunities are endless. Oh, and there's working for a company where every new startup seems to be an "Uber" for something. It's exhilarating to be a part of this thing!

Cons: The insane growth comes with its downsides: Uber is no longer a scrappy startup where everybody knows everybody and you're all at least aware of what others are working on. Nowadays, it's taken on a bit more of a "corporate" feel with levels of management and computer policies. Uber has handled it pretty well, but it's a bit of a whirlwind to go from one to the other.
