Interview Query

Doordash Mid-Level | April 2021

Company: Doordash

Location: San Francisco, CA

Role: Software Engineer Data

Level: Mid-Level

Outcome: Rejected

Chatted with a recruiter (Nadia) over the phone. She was relatively pleasant. Explained to me the team i’d be working on and the opportunities for advancement. Laid out the interview process pretty clearly. Next step was a technical Phone screen. They asked me some simple questions about sql and some brain teasers. I wasn’t able to solve the brain-teasers so they rejected me.

Overall it was a pretty fair experience. Guess i’ll study harder next time.

What kind of technical questions did you get asked?

  1. Explain the difference between an inner and an outer join.

  2. Simon says you have two containers, one holds 3 gallons, one holds 5 gallons, unlimited supply of water. How do you get exactly 4 gallons in a container?
