One thing I found odd during this whole process was that neither the recruiter nor the person scheduling the interviews ever spoke with me on the phone, leaving me to often wonder what the end-to-end pipeline of the interview process looked like. I had two phone interviews, both tech screens. The first was with the guy who I think is the hiring manager/leader of the group I was applying to join. That call focused on machine learning combined with a business case. The business case was really interesting and was a scenario that the company often faces but doesn't have a clear "good" answer, so thinking about pros/cons of different suggestions and approaches is key (as well as understanding how to model and measure the complex data that Uber has). This first call went quite well and I enjoyed speaking with the head of the team. I was passed on to the next screen, which was a coding interview with another member of the team. The coding question was also quite interesting, with a fun twist. I discussed my thought process out loud while working through each piece of the problem. The interviewer seemed to be impatient and interrupted me a LOT. Often when he interrupted me, he would straight up tell me the answer instead of letting me work it through and tell him what I was thinking. This made it difficult to show my proficiency in anything, but was effective in convincing me I did not want to join this team.
