Pros
Uber is the dream job if you like solving problems, winning, being creative, finding ways to get over being stumped, and seeing your work take effect fast. Its high-stress, high-creativity, high-reward environment is addictive and and fun. The company strives to keep the bar high by only hiring flexible, intelligent, talented people. That, combined with the standard of transparency we have here, makes this an awesomely empowering place to work. Everyone has agency to move around and take on harder projects because of the honest, open communication. The pace is fast, but the speed isn't driven by numbers and money and quotas. We're all working on something that's already being used around the world all the time by millions of people, so we have to solve problems quickly to keep users (especially as we grow in our new launch cities) happy and safe.
Cons
There's a lot of work to be done before we can reach a stable place. Even as we grow, it feels like a start-up with long hours and a free, flexible management system. To me (and other good fits) these are actually pros, not cons. You have the freedom to solve big problems the way you think is best. Everyone here works a lot, so if you have a vibrant life outside of the office, you'll probably struggle. Even after a 13-hour day, I feel like I have a good work-life balance just because I find work so fun and my coworkers so bright and quick and funny; I'd rather be in the office than at home.
