Time to explore new opportunities, so I submitted my resume to a few top Valley companies and startups, including Uber. I was contacted by the recruiter a few days later after my online submission.

1. Recruiter initial phone call (30 mins)

2. TPS (1 hour) You need to solve the coding exercise via an online code-sharing editor, with some follow-up discussions.

3. Take-home code challenge I spent a weekend building the solution and making sure I liked what I submitted. I got feedback the next day. Amazing efficiency.

4. Four onsite interviews (4-5 hours) at Uber HQ I jammed with a group of Uber engineers, plus a nice onsite lunch break. Each interview was designed with two engineers, except for the culture fit one, which was 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 were reasonable. I marked the interview as difficult in the sense that you definitely want to be well-prepared. There were quite a few problems I had never seen before. Know your stuff well, and you should be OK.

The interview process was very smooth. I had no issues with my onsite travel reimbursement, although it took about three 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, which is happening on an incredible scale. And all the engineers I met were super cool, sharp, and resourceful.
