DoorDash Data Scientist Interview Experience — Seven Rounds Including a Take-Home Prediction Task

The interview process was as follows:

1. Round 1: HackerRank assessment — SQL plus some data analysis questions.
2. Round 2: HR screen — talked about why I was interested in DoorDash, my project experience, and why I was looking to switch jobs.
3. Round 3: Hiring manager interview — mostly about my project experience, plus a DoorDash case question.
4. Round 4: Take-home — given a DoorDash dataset to build a prediction on, plus a few SQL questions.
5. Round 5: Interview with a manager from another team — mostly about my resume, plus some behavioral and case questions.
6. Round 6: Interview with a senior manager from my own team — mostly about my resume, behavioral questions, and case questions.
7. Round 7: Another interview with a senior manager, still from my own team — continued going over my resume and behavioral questions.

Overall it felt fine. The pace was pretty fast, and the interviewers were all pretty friendly. The questions were moderate difficulty — it mainly came down to whether your thinking was clear and your logic made sense.
