Uber Data Scientist interview questions

Same experience as last DS interview person. I applied online and a recruiter reached out to me. He/She wasn't helpful or forthcoming with the different DS positions, even when I asked. Was asked to do an offline exercise which was very open ended, one data science-y and one programming. Could do it in any language. The DS questions itself were worded ambiguously, to begin with. Was given a week to finish and I did it and wrote a 7 page article (as they wanted a detailed analysis!) with lots of plots and scripts(just like the last guy!). I sent in my submission and got a reply almost immediately saying we are not interested! The quick reply makes me certain they didn't go through my submission. My opinion is to not waste your time and just use it to practice your DS skills.
