And this was presented as a typical day, not a rare "everything is on fire, all hands on deck" thing?
I don't want to rat out the two people who told me since they are easily trackable but i heard it from two different teams. I also heard it from the intelligent spend team.
This wasn't just from Uber people either. I honestly really wanted to work at Uber and told my friend at Square and he told me he heard the work environment was "toxic". I also told my mentor at my internship that i thought Uber was cool and he said his friend worked there and had insane hours. Finally, my roommates cousin started working at Uber a year ago and has echoed the previous statements.
Once again, this is all anecdotal but it's hard to ignore the signs when I've had them from so many sources. I sincerely do believe in Uber's mission and have wanted to work there for years so i'm not trying to be biased at all.
edit: And these toxic environment comments were this summer.
