I applied through a recruiter. The process took 3 weeks. I interviewed at DoorDash (San Francisco, CA) in Jan 2025
Interview
1: Recruiter Screening
2: Technical Interview - SQL and Case Study
3: Panel Interviews - 1 Product Partner, 3 Case Studies
4 Case studies over the course the interview was complete overkill. It's not like they are distinct, there was so much overlap it's unclear if they want you to somehow approach each one differently or... ?

I applied through an employee referral. I interviewed at DoorDash in Jan 2026
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

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.
