Uber Data Scientist interview questions

Screening interview consists of SQL and product sense or analytics questions. SQL was needlessly difficult. They had a bunch of seemingly related questions that are, I believe ordered by difficulty level. Interview skipped first of couple of questions and went to one of the middle questions. After answering she moved to another question which were supposed to be an add on to the one I just answered but really was not. In the end it seemed like I was just put thru a SQL wringer just being asked follow up questions that were in themselves full questions that required a good amount of time to solve. It just seemed they wanted it to be difficult just to be difficult. It was a bit exhausting.
