Great chat with the interviewer.

Solved the interview question with optimal time and space complexity, while explaining my approach to the interviewer from time to time.

We had more than 10 minutes left at the end of the interview for questions and answers. We had a great discussion about the company's future plans and current teams.

I was considering joining them, based on the future prospects of the company. But to my surprise, I got a rejection.

FYI, I have been an interviewer for my current and past companies for many years. The only reason for rejection, in this case, I can think of, is that their position was no longer open.

@Opendoor recruiters Please let candidates know if this is the case.

Simple question compared to FB, Google, Uber phone screen.
