Uber Operation and Logistics Manager interview questions

I was called up and selected for an interview for the Logistics/Operations Manager role. I work on Wall St right now so I make about $90K base plus bonus. During the phone interview, I was told that I would have to take a reduction in the salary, but I'm compensated by equity/stock options. I spoke to another current Uber employee, who indicated that the salary is closer to $70K, but that his stock options will likely be worth $500K (I think this was an exaggeration) when Uber is worldwide and fully implemented (probably 10 years from now). When you think about it from a financial perspective, it really is not worth it for Wall St bankers/traders. Uber requires you to work 13-16 hours a day, including weekends, and wants to pay you a $70K base with stock options that will likely get extremely diluted (just look at how many job postings they have, that class of shares will continue to get diluted as they hire more people). Anyways, at my current position in 5 years I will likely be making $180K plus bonus and working 10-14 hours a day, and in 10 years it should be $300k plus bonus - so this did not really make sense for me. I want to point out that it seems that Uber may be data farming through the hiring process. The questions they ask are mostly around what you would do different at Uber, and what your ideas are for the company's growth. I think that many of these job postings may just be methods of data farming to obtain new ideas for the company, instead of the company actually looking to fill the spot. Just a thought, unlikely but still possible - if this is the case, then it is a brilliant way to get new ideas without actually paying you for it. That is pretty much why I withdrew from the interview process and did not want to proceed to the final round.
