      Data Scientist Interview

      Oct 3, 2021
      Anonymous interview candidate
      No offer
      Negative experience
      Average interview

      Application

      I applied online. The process took 2 weeks. I interviewed at DoorDash in Jul 2021

      Interview

      Phone screen experience (1hr) * 30 minutes case study: very vague. interviewer didn't help at all. I was just talking to myself. very little feedback nor any facial expression. * 30 minutes SQL questions: again very little feedback. They (two interviewer with one shadowing) just copied and pasted the questions to coderpad. You'd have to be really fast because there are at least three questions. Based on the phone screen experience, I think they are seriously wrong in choosing right people for right positions.

      Interview questions [1]

      Question 1

      * case study: what would you do if doordash do this or that? * sql: all of them asking ratio.

      Average interview

      Application

      I applied online. I interviewed at DoorDash

      Interview

      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.

      Easy interview

      Application

      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 questions [1]

      Question 1

      SQL - CTEs, Joins, Window Functions, Rank Case Study - If bikers were added in the market to deliver food.
