Uber Data Scientist interview questions

Applied online. A recruiter reached out to me with a list of screening questions. In the next step, she sent a take-home case to finish in 7 days. I work in the field of data science for 10 years and I spent around 15 hours and analyzed the data with multiple tools and provided recommendations. Then after a few days, I received an auto-rejection note. I asked for feedback and they gave none. Such a waste of time and effort.

Two weeks after submitting my resume online, I was contacted by an HR generalist. She sent me a short questionnaire with questions like why are you interested in Uber? the immigration status, etc. The HR lady then set up an exploratory chat with a hiring manager and during the chat, we talked about my overall background and experience and why I was interested in Uber. A day after the first chat, the HR team sent me a questionnaire to fill out asking about my visa status. After finishing up the immigration questionnaire, another hiring manager wanted to set up a technical phone screen with me. During the 45-minute phone screen, in the beginning (about 10 minutes or so), some basic questions like difference between for loop and while loop, meaning of inner join are asked. And later I was asked about a case where I went through the steps of a data science project with the HM. My background is in transportation engineering and did not have much knowledge about data science when I had the interview. But the HM was really friendly and helpful, she listened really carefully to my answers and guided me through the case. I got rejected after the technical phone screen but still a really positive experience :)
