Everything you've heard about Uber is true - doubly so for the LA office
Pros
Workload is fairly light compared to other areas of the company. If you play your cards right, this is much less than a 9-to-5 job if you're good at acting like you're working during the day. In addition, no one checks your work in this office. This is a byproduct of most colleagues being completely checked out and not having the mental capability to understand anything beyond basic arithmetic. For what it's worth, some of the benefits are nice. You get 15 free trips up to $15 a month, and lunch is served every day. The office is also in a great location, so it's nice to meet up with friends after work.
Cons
Most of middle management is completely incompetent. This is because the competent individuals have left for HQ, so only mediocrity is left. This office also promotes heavily based on seniority, so if you're neither, I recommend you look for another job. Surviving in this office has nothing to do with merit. It is more important to fall in line than to do anything substantial. Keep your head down, act like your boss is God's gift to the world, and find a way to set yourself up for a successful transfer after the 6 months.
