I applied through an employee referral. The process took 1+ week. I interviewed at Opendoor (San Francisco, CA) in Nov 2017
Interview
Overall I had a great experience interviewing with Opendoor. I really liked the people I met and think the company is headed in a great direction.
Introduced to a recruiter through a friend. Did a phone call meet and greet about what I was looking for, went through a technical phone screen, did an all-day on-site meeting six different people - 2 technical interviews, a lunch culture interview, and 2 system design interviews.
Then, after an offer was made, invited back to sit in their engineering all-hands monthly and a team weekly meeting, which were both great experiences.

Question 1
Implement a well-known data structure (a specific one named by the interviewer) in the programming language of your choice
Failed at HR call. Profile might not be that much match, they are looking for backend leaning role but I did more front end works instead. HR might not look up my resume carefully.
I applied in-person. I interviewed at Opendoor (Seattle, WA) in Oct 2025

Very easy and straightforward very nice people enjoyed the conversation that we had a lot and benefitted a lot from it so I would thank them for that
Overall the interview is structured and chill and straightforward with a pretty laid back vibe
I applied through university. I interviewed at Opendoor
Interview
There was a phone screen which was followed by an onsite interview with 4-5 interviews, some technical, others behavioral. It was interesting that they included some ML-based questions in the SWE interview. Afterward, I heard back pretty quickly.
