I applied online. The process took 2 months. I interviewed at DoorDash in Nov 2024
Interview
The call with the recruiter was straightforward and to the point. The second interview was a one-hour session split equally between product knowledge and SQL. The product knowledge portion was simple—if you’ve watched YouTube videos on FAANG Data Scientist interviews, you’ll have a good foundation to do well. The interviewer was a sweet person and they even mentioned I did very good.
However, the SQL portion is what caused me an issue (I think). As a Data Scientist with six years of experience, including time at Meta, I found their approach outdated. It felt like something from the 2010s when companies were unsure whether they needed a Data Scientist or a Data Engineer.
The interviewer didn’t turn on their camera, which made the interaction feel disengaged, and they seemed distracted throughout. The SQL prompt wasn’t overly difficult but was highly impractical—something you’d never encounter in a real-world scenario. To make matters worse, the coding environment didn’t execute your code, forcing you to mentally process everything under strict time constraints. It felt more like a test of memorization than actual problem-solving skills.
My main takeaway was, “DoorDash tries to present itself as a FAANG-like company, but their analytics department is stuck in the past.” If you’re preparing for a SQL interview with DoorDash, I honestly don’t know what would adequately prepare you for their outdated and poorly administered process. I thought we had moved past asking irrelevant SQL trivia in technical interviews.
For interviewers, make sure you answer the question fast and hopefully the employee administering your interview will be more engaged than mine! Good luck!
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.

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.
