I applied through a recruiter. The process took 4 weeks. I interviewed at DoorDash in Feb 2024
Interview
The process is quick and standard, starting with recruiter call > tech screen (1h of SQL + case) > onsite (3 45-min case interviews, 1 behavioral with a business partner). It's not necessarily hard but you have to prep very well (understanding the business and its most common challenges) to be able to navigate the amount of DD specific problems they ask. The kind of questions they ask are not really great to evaluate candidates' sense of data and problem solving skills and would probably benefit people with very close background (e.g. coming from Uber) or those with a ton of prepping on this specific problem area. Overall I have a positive experience with most of my interviewers - they're nice and some of them even give instant feedback on my answers + patiently guide me through the case.
phone screen and Zoom meeting with the hiring manager for 30 minutes. After that, I did a take-home assignment and submitted it in 72 hours, but i did not pass this one
Interview questions [1]
Question 1
What is your experience, and why are you interested in this position
I applied through a recruiter. I interviewed at DoorDash (São Paulo, São Paulo) in Jul 2026
Interview
Quick HR screening where they talk about the role, salary, benefits and how the entire hiring process works. Then there is the technical screening. Round 1 is a SQL round (hackerrank medium-level) with questions that are resemble the actual work that they do there. There are 4 questions, but there's barely any time for the last question and I was told it's not actually expected that you solve it all. Round 2 is a case study, just an open-ended business problem and you have to walk them through how you would deal with it.
Virtual onsite is 4 rounds - 1 round with a cross-functional partner (behavioral) and 3 case studies just like the technical screening, they're just checking for consistency here, there's nothing new to expect.

Question 1
SQL were very trivial questions just involving CTEs and group bys. 3rd question was the hardest and required you to compute a metric relative to the last month, so do refresh your knowledge on window functions.
I applied online. I interviewed at DoorDash (San Francisco, CA) in Jun 2026
Interview
1. First round of interview was 30 min SQL (very easy) + a case study
2. Second round had 3 case studies and one cross functional interview
Interviewers were kind. 2 of the case studies were straight forward, one was very ambiguous.

Question 1
experimentation, metrics, diagnosis, LTV, Opportunity sizing in an ambiguous setting were you can't run experiment and you have to make a lot of assumptions to navigate through the ambiguity.
