I applied through a recruiter. I interviewed at DoorDash in May 2024
Interview
Was contacted via LinkedIn. Set up a technical phone screen. 30 mins of SQL, 30 mins of a product case study. The SQL was via CoderPad, you can't run the code. SQL was pretty medium difficulty, ranking and window functions.

Question 1
Sales are down in the LA area. How would you diagnose this problem?
I applied online. I interviewed at DoorDash in Jun 2026
Interview
1. SQL - 4 questions, Easy - Medium. Window functions and aggregations
2. Case Study question - open ended conversation, interviewer guides you along well. looking for structure and thought process here
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.

Question 1
SQL - Window Functions, Rank, Lag. Case Study - Bikers an an option for food delivery.
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.
