Pros: First and foremost, I truly believe in Uber's mission and have a deep conviction of the good that Uber is bringing to society. This gives me a tremendous deal of satisfaction. By disrupting the monopolistic taxi industry, Uber is making transportation more efficient and bringing value to: * The drivers, who generally have much better pay than driving a taxi (because Uber gives drivers a larger cut of the fare than a taxi company would, and because Uber makes rides more efficient so that drivers have less downtime and thus more trips). The drivers would also enjoy flexible hours and being their own boss (interestingly, this is consistently the #1 reason why drivers love Uber, at least from my personal experiences talking with dozens of drivers). * The riders, by giving them much better riding experiences (courteous and friendly drivers, cleaner cars, convenience in hailing a car, great customer service), as well as cheaper rides. * The society, by making more jobs (we are creating 50,000 jobs a month across the globe) and taking inefficiencies out of our economy. * The environment, by reducing the need for self-driving and car ownership, and encouraging ride sharing. Uber could make a potentially very large impact on our environment. Second, the reason why I love working for Uber is the people I work with. I am fortunate enough to be working in a team with both great leadership and great colleagues. Here, we really work as a team. Everyone is very talented, works hard, and helps each other, and we learn from each other and grow. And from what I know, this is not true of our team only but a general culture across the entire company – you don't get this everywhere. Last but not least, I am also fortunate enough to be working on a problem that's both technically/intellectually challenging, as well as contributing tremendously to Uber's business bottom line. Being able to see our work make a real business impact gives me a lot of satisfaction working here.

Cons: Being a relatively young company that grows exponentially fast, we do have to work pretty long hours. Personally, I don't mind, as I really love this company and I voluntarily work after I get home and on weekends too. I think this is just part of working for a start-up company one truly loves.

Pros: Opportunity for impact. The per-capita impact for each engineer is higher than at most other tech firms. At Uber, each engineer has a real impact on the company's bottom line. This really drives the ownership culture and is inspiring to see. Culture that promotes standing up for what you believe in. If you feel strongly about something, the company encourages you to voice your opinion, even if there's a large discrepancy in rank. At the end of the day, the right idea should win. Exponential personal growth. The engineers who survive here will experience rapid growth in engineering abilities. I learned more in the first 6 months at Uber than I did in the previous 2 years at a large tech behemoth. Competitive compensation. Convenient perks: free food, monthly credits for Uber and UberEATS.

Cons: Longer than normal hours (compared to other SV firms like Google and Facebook). The longer hours aren't imposed. It's more like you feel inspired to build or improve something that you own. Bad brand PR. Uber is one of the most vilified tech companies. While most employees believe these opinions to be based on misinformation, it's demoralizing to know some people see Uber as the "bad guys".

Pros: Smartest and most passionate people. Everyone in the team is excited about the impact and opportunity. People believe Uber is changing the way people live. This is the kind of work that, every morning when you wake up, you feel like your achievement will be rewarded and you are proud of what you are doing.

Cons: Since the company is on a huge growth path, the office is getting crowded. The working environment is very stylish, and there is already a plan to expand the office space.
