I applied through an employee referral. The process took 4 weeks. I interviewed at DoorDash in Sep 2024
Interview
30 min SQL and 30 min case study.
The person who conducted the SQL portion was very unprofessional. There was no introduction or even a 'hi'. She jumped right into the questions. For the 4 questions, she didn't type out any but assumed that I would remember them by heart (she wasn't very clear when stating the questions). When the internet signal got a bit messy and I asked her to repeat a question, she told me she had already said it before.
What's most bizarre to me is that when I wanted to reuse the table I created in question 1 for question 2, she insisted I type the query out again. The same applied for questions 3 and 4. I had to retype everything. I ran out of time at the end, which I think I could have avoided if she had been more professional and reasonable. It was one of the worst interview experiences I've had. I am glad I was rejected because it shows how badly trained their interviewers are and that the company culture is anything but compassionate.
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
