I applied through an employee referral. The process took 4 weeks. I interviewed at Uber (Chicago, IL) in Sep 2014
Interview
You are required to do a creative, a phone screen, and an interview panel with about four to five different people. It's lengthy, but typically they are looking to hire the right person for the role which is imporant.
I applied through a recruiter. The process took 3 months. I interviewed at Uber (San Francisco, CA) in Oct 2017
Interview
The entire process is ridiculous and designed for attracting arrogant brogrammers. Each of the people who I interviewed with was an a-hole (this was not a single occurrence) but the worst was the treatment by the hiring recruiter -- lies throughout the process, lack of transparency, and just straight up lack of ethics (he even gave dirt on the company trying to downplay the previous management). If Uber wants to succeed, they need to make a wholesale cleanout of their staff and not just their top management. Not one of the people interviewing seemed to have any depth of real experience, and the attitudes by the product managers specifically was completely prickish.
I stuck out the entire process (3 months) just to prove I could get the role, but after each stage, I was more sure that I was not going to ever accept going. The new CEO does make it tempting, but I don't see any indicators that they are going to get rid of the rank and file goofs who seems to be throughout the company. (overall, I interviewed with about 13 people (not including HR). 10 of those were in person. They also asked for a project up front, which I didn't mind doing because it was interesting but was ticked that it played zero during the actual interview. During the interviews, timing was always off (went 2 hours longer past 5pm than originally planned on my first site visit), people did not show up three times leaving me just sitting there. During one of those times, I just stood up and walked around the building which makes feel great about their sense of security, and only 3 of the interviewers seem to have actually done any preparation. Their 'jam session' is a complete lie - it is just an interview with more than one person, both of whom had did not seem to have any preparation done. There was no 'jamming' -- no collaboration of ideas or joint development of solutions. It was just two people asking random questions which seemed to reflect the stupidity of PMs who have never developed anything before.
If you get an offer to interview at Uber. Don't do it unless you are really early in your career and want a name brand, or you are desperate. This is not a place to go if you have skills and want to work with either people you will learn from, or people who seem open to working with others.
Interview questions [1]
Question 1
Standard questions that you can find in Cracking the PM Interview. Questions from Designers and Engineers, were basic 'how do you manage conflict' type questions. Or 'how do you like to work with Designers/Engineers'
The interview process was at best Lazy and Unprofessional. After contact recruiter it took almost 2 weeks to get back after follow up contrary to what was discussed during first contact. My first interview was with Junior level product manager who had no background in the area she is working in. Could not answer basic questions about the business unit instead asked me what I did in my prior jobs on those issues. She could comprehend B2B space and looked confused. Instead of the 45 minutes schedule she decided that she has another meeting after 1/2 hour left.
