Opendoor fullround interview experience
182
Apr 08, 2026

I applied for a senior fullstack position in Seattle

Recruiter Screen:
Literally asked me nothing, just talked about the interview process

Tech screen:
Part 1) Build a key value store that suppors operations add, update, delete
Part 2) Support operations isExpired, sleep(time), setTTL(ttl)

Interviewer seemed to hate his life.

React Interview 1:
Build a react app that makes a web request for a list of images and renders rows and columns dynamically as window size changes while keeping images the same size.

Very CSS focused which I wasn't prepared for since I am a mobile dev.

React Interview 2:
Part 1) Debug a rendering issue with the scabble board. It's a css margin issue on the p tag.

Part 2) Make a network request for game data and render the scrabble board. They asked me to implement the first two buttons here https://scrabble-interview.vercel.app/frontend/game

System Design:
Design Job Queue for Opendoor ops tasks (essentially design Jira).
Imagine 100s of people using the same Jira board. If someone marks a task complete, everyone else should see the changes in real time.

Behavioral:
Very conversational, none of that "Tell me about a time you..." STAR bullsh*t. Mainly just talking about a couple projects I worked on.

Result:
FAILED. I don't know css at all, I didn't think the react interviews would be so focused on css. I know react very well, but in a mobile context only, so no css.
