DoorDash Data Scientist Interview Experience — A Seven-Round Loop with a Take-Home and Three Manager Interviews

The interview process went like this:

Round 1: HackerRank assessment — SQL plus some data analysis questions.

Round 2: HR screen — talked about why I was interested in DD, my project experience, and why I was looking to switch jobs.

Round 3: Hiring manager interview — mainly talked about project experience, plus a DoorDash case Q&A.

Round 4: Take-home — given a DoorDash dataset to build a prediction on, plus a few SQL questions.

Round 5: Interview with a manager from another team — mainly talked about my resume, plus some behavioral questions and case Q&A.

Round 6: Senior manager interview from my own team — mainly talked about my resume, plus behavioral questions and case Q&A.

Round 7: Another senior manager interview, still from my own team — continued talking about my resume and behavioral questions.

Overall it felt okay. The pace was pretty fast and the interviewers were all pretty friendly. The questions were about average difficulty — mainly they want to see that your thinking is clear and your logic makes sense.
