Uber

I came to Uber concerned about rumors I had heard about a cutthroat culture. I needn't have worried.

Uber is one of the most collaborative environments I have ever worked in. Whether it's answering a question about their code, helping to debug, or working together on a feature, people have been uniformly enthusiastic about helping their co-workers. Perhaps this is because everyone's stock grants are so large that people just want the company to succeed :)

Uber is good at pruning out busy-work. Everyone I know is working on a project that I characterize as 'critical'.

The quality of the engineering team is excellent. Super bright, hard-working, and they care about building the best product they can.

Work-life balance suffers a bit in this environment. Don't come here to go on cruise control. Uber demands hard work from everyone, and consistent 8-hour days are rare.
