I applied through an employee referral. The process took 4 weeks. I interviewed at DoorDash in Sept 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.

Interview
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
Interview questions [1]
Question 1
How to evaluate bike delivery as a new dasher type?
I applied online. The process took 1 week. I interviewed at DoorDash in Nov 2025
Interview
It was a series of two rounds, one was a SQL round, and the other a case study. They provide ample material to prepare for the interview beforehand. But be prepared for changes in the time length or order of interviews on the actual day. The SQL questions will be easy to medium.

Question 1
The case study focuses on either two or three of their system: users, dashers, and merchants. Practice thinking by putting yourself in each role and evaluating the impact of a decision on you. Focus on metrics as well.
1. The recruiter initially contacted me via LinkedIn.
2. The HR phone screen was straightforward, focusing on my background and salary expectations.
3. The technical round lasted one hour, split into a 30-minute case study and a 30-minute SQL assessment.
