I applied through the Jobs On Demand promotion and the whole process took 5+ weeks from start to finish.
After sending many "encouraging tweets" and creative instagram posts, I was given a creative assignment to showcase my skills. The assignment ranged from 3 idea proposals for Uber Promotions, to replying to angry tweets and emails, to using KPIs to analyze the expected cost of new promotions. The whole project spanned 15 pages of writing and it was encouraged to be completed over the weekend.
After this homework assignment, I was given a skype interview with a community manager. The interview was very short and the manager asked me to describe the creative assignment to him. I couldn't tell if he read it or not but I got comments about my ideas and how they meshed with the uber brand (think music, everyone at uber is a millennial.)
After this I was invited to an in person interview that was supposed to take 90 minutes. This interview was with the senior marketing manager and the head recruiter. In the email I was told to bring nothing and the interview with the recruiter lasted 50 minutes as she went over my resume and discussed company culture. Many times during this process it was emphasized that Uber employees work 60+ hours a week and they have very long days. I have to be ok with easily spending 10 hours a day including weekends and holidays in the office. There is remote working, but sick days and not showing up is very discouraged. I was also told that the first few months would be mostly responding to angry emails and tweets and eventually when the next round of new hires come in that I would transition into a marketing role.
The second person I talked to was the senior manager, who talked to me for 10 minutes. When we sat down she was confused that I did not have my resume even though I explained to her that the recruiter had it and took it with her. My only question then was "So why do you think you are qualified to work here?" and I tried to explain my previous positions to her as succinctly as possible.
There were no further questions after that and the interview ended half an hour early. I was still in shock as I left the office that I was told to not bring anything and the senior manager didn't even want to try to see why the recruiter thought I was a qualified candidate.
I wasn't given an offer at Uber and my comments on my interview focused on how the staff felt I didn't have the skillset to expand the company.
