Uber Sourcing Manager interview questions

After submitting my resume, I was contacted by a recruiter to setup a phone screen. That was followed by a phone interview with the hiring manager. I was next given an exercise to complete with real world Uber contacts and companies. It was reviewing and marking up a contract for a specific service. After submission, I was told I was not moving forward. I agree with other posts that they are idea farming to help with their workload. It's not so much because of this experience but the position was re posted several times for many months and isn't really one that should be that difficult to fill. Also, I was recently contacted via email by a different recruiter for the same position but slightly different title. He claimed it was a brand new position. When I responded and mentioned the above experience, I didn't hear a word back. .
