Opendoor Software Engineer interview questions

I responded to an outreach email and had a screening call with a recruiter, followed by a conversation and technical screen with the team's technical lead. I had a followup call afterwards to discuss some more questions I had about the role before moving to the onsite interview. The onsite interview consisted of three technical screens (system design, backend, frontend) followed by a chat with a product manager and the general manager overseeing the greater org. I went through all the interviews and got a call stating they would like to make me an offer. I had a couple of negotiation calls, then waited for two weeks with no response. After emailing to ask for an update, I was told that the team was now interviewing other candidates. The week after that, I had a call with a recruiter who informed me that the team was now in fact no longer hiring for the position anymore, but that I would be able to talk to the hiring manager of another team doing very similar work, and if the conversation went well, work for that team without having to go through the interview process again. After the conversation with the second hiring manager, I never heard from the company again.

The interview consisted of 5 rounds. 1 initial screening round and 4 technical rounds. The company doesn't have a centralized tech stack or a clear vision. They work on multiple tech-stacks and a developer is expected to contribute and pick up new tasks and technologies as per requirement
