Pros
I came from a management consulting background to the Ops team, and could not be happier. It's been less than a year, and I can genuinely say I made the best career decision moving to HQ and working here. As to why.. (1) Smartest, most intellectually curious people who are data driven and can execute - I am constantly amazed by the intelligence and background of everyone on the team. Some of the brightest people I've met in my life, and I am so lucky to be learning from such diverse backgrounds and approaches to thinking. One of things that was missing from management consulting was true hands-on execution. Uber is about bringing forward the brainpower + ability to execute, and it's an incredibly fulfilling combo. (2) Hustle and energy - Enthusiasm / Uber love for the product and team is unparalleled. Everyone looks out for each other to hustle, pitch in, and get it done, regardless of what it takes. (3) It's just fun - I really look forward to work each day.
Cons
Difficult to come up with cons, but probably work-life balance (not unheard of in the tech world here in SF). Uber does end up seeping into what I think about 24/7, and end up working quite a bit into weekends, etc. but that's also a personal decision.
