Time to explore new opportunities, so I submitted my resume to a few top Valley companies and startups including Uber. Got contacted by the recruiter a few days later after my online submisson. 1) Recruiter initial phone call. (30 mins) 2) TPS (1 hour) You need to solve the coding exercise via online code sharing editor. Some follow-up discussions. 3) Take home code challenge. I spent a weekend on building the solution and making sure I like what I submitted. I got feedback next day. Amazing efficiency. 4) 4 onsite interviews (4 - 5 hours) at Uber HQ. Jam with a group of Uber engineers, plus a nice onsite lunch break. Each interview is designed with 2 engineers except the Culture fit one which is a product discussion with one of the engineering managers. I did some coding questions on my laptop. 5) Wrap up with my recruiter. All questions are reasonable. Marked the interview as difficult in the sense that you definitely want to be well prepared. There were quite a few problems I never saw before. Know your stuffs well -- you should be OK. The interview process is very smooth. I have no issue with my onsite travel reimbursement, although it took ~3 weeks to get it completed. I got a call in the next one or two days after my onsite with an offer! The package is excellent. I chose Uber over other offers/opportunities because I really believe in Uber's mission that is happening in an incredible scale. And all the engineers I met are super cool, sharp and resourceful.
