Uber People Development Specialist interview questions

Was contacted by recruiter after submitting my resume for less than a week. Recruiter asked standard questions but also provided some good background about the team. Let me know pretty quickly that they decided not to move on.

I had interviewed with Uber previously (a review for another time) and reached out to the recruiter when I found new opportunities open on the website. After a phone conversation with the recruiter, I had video conference interviews with the hiring manager and a member of the team. After this I was informed they wished to bring me onsite, but asked me to first complete a "creative exercise." It took them 12 days to send this exercise and I was given 48 hours to complete it. I spent 5-6 hours working on it. I received a rejection e-mail not even one full business day after submitting my work. The fact that I was rejected didn't bother me as much as how I was rejected. My work was solid and I just don't think it's possible it was actually reviewed in the time they had it. Plus the exercise was always communicated as being a part of the onsite interview process, not a test to get that interview. My gut is they filled the role internally in the intervening time, which is fine, but just don't give other candidates the run around. Also, rejection over email after I've interviewed with two members of the team and have been through a previous process is just terrible recruiting. The entire recruiting process with Uber left such a poor taste in my mouth I actually converted to being a Lyft customer. I know this sounds like sour grapes but I've had other non-successful recruiting experiences that I feel very positively about overall. Who knows, maybe I just had a bad recruiter.
