I interviewed at DoorDash (San Francisco, CA) in May 2026
Interview
they only test sql, seems like median level but only 30 mins to do 4 questions. not sure how well I did. For the case study, I feel like I been asked a werid question : the interviewer start with "if we go back in time XXX " I know I'm done. The question is nothing like I prepared.

Question 1
how to do experiment for some new bussiness model. and how you design test to validated it.
I applied online and after about a week, I received an email from the recruiter with a 15-question questionnaire. The next day, they scheduled a 1-hour interview consisting of a 30-minute case study and 30-minute SQL round.
I spent significant time preparing and felt the interview went well. However, I received a rejection within 15 minutes after the interview ended.
Honestly, the process felt discouraging. It almost seemed like the interview was conducted more for internal interviewer training than genuine hiring consideration.
If you're interviewing there, I’d suggest treating it mainly as practice and interview experience rather than getting overly invested in the outcome.

I applied online. The process took 1 week. I interviewed at DoorDash (Chicago, IL) in May 2026
Interview
Good thing they don't have recruiter screening. The first step is SQL (30 mins) followed by case study (30 mins). Looks like they just interview for the sake of training their employees. Literally waste of time preparing for Doordash. I reading all the reviews about toxic work culture. I should have taken it easy. The recruiters just give 1 min intro.
I have completed all the SQL questions and even explained them to the recruiter. Case study also went well but I have received rejection within 3 hrs. Its disspointing that I spent whole week preparing for it even after reading the reviews.
