I applied online. I interviewed at DoorDash (Sydney)
Interview
SQL round: The interviewer was friendly, and the questions were at the LeetCode medium level. Case study analysis: Unfortunately, the interviewer didn't seem to understand their role properly. They appeared to have predefined answers for the case study, limiting the exploration of different possibilities. This behavior came across as unprofessional and gatekeeping.
Other Senior Data Scientist Interview Reviews for DoorDash
The recruiter reached out through LinkedIn. First round was an interview with the hiring manager, then a technical interview including 4 sql questions and one case study in one hour. After passing this step, I moved to the onsite which included 3 case study and a meeting with XFN.

Question 1
What does this sql code do? and if we want to change it to monthly what should we do
I applied through an employee referral. I interviewed at DoorDash (New York, NY) in May 2026
Interview
The interview process was first a recruiter screen, then two screening interviews with SQL and a case study, then 2 case studies, one hiring manager interview, and 1 cross-functional partner interview. These interviews are similar to what I would expect for data scientist interviews, but they aren't layups. I expected to be ready after acing the screens + (in my opinion) one of the case studies. But then in one of them they were looking for me to use some concepts I wasn't familiar with, so I bombed it and spent most of the time jumping around to adjacent topics that were similar but evidently not as good. They're pretty quick with the interview process, and I felt they were professional. I just wish it had gone better

referred by a friend, and had the 1st round of interview consisting of 30-min case + 30min coding . The case question is not hard with pretty vague, but they do care a lot on how to translate the solution into technical solutions
