I applied through college or university. The process took 3 days. I interviewed at Uber (Calcutá) in Dec 2015
Interview
One round of analytic and one round of recorded interview. Followed by personal interview. Easy interview process. Analytics included CSV file download and do analytics. It also had essay type que. I cracked it quick.
HR screening - take home assignment before 1 day with HM - Hiring Manager round(Behavioral + sharing of assignment - another take home case - presentation with HM, skip manager, 2 member/leader from other teams
Interview questions [1]
Question 1
they will deep dive into your experiences, also how frequent you use those data tools
Five to seven rounds of interviews, tests and presentations just to get a “no, thank you” at the end without much of a feedback. Acceptable for regular recruitment but not after weeks dedicated to the process.
Pretty easy at early stages - just need to know about supply and demand basics. Analytics test is harder, but manageable if you know Excel well. They are definitely interested in your problem solving abilities and ability to "get things done" with minimal supervision.
