Politics. Too much of it. Left the company within a year since I could not handle the continuous nepotism, criticism etc of work. We are expected to work like crazy and anyone who does anything other than work is frowned upon. No work life balance. Not worth joining now that the upside is also not much.
Recruiters talk trash of Uber being a $500 B company in the future. I would be surprised if they even sustain their current valuation.
