This was a 60-minute HackerRank challenge. They followed up after about two months for a video technical interview, which was sort of like pair programming.

I still don't know why they rejected candidates, as many others have reported a similar experience. I was asked only one question, and I coded it correctly in one go, passing all test cases without external help.

They mentioned that you could take help from external sources if needed and that you had to share your screen throughout the interview. It's quite strange why they still reject candidates.

It felt like a waste of time. I wouldn't even bother preparing for this interview. The question was super easy.

Given a list of HashMaps and a key, find the HashMap corresponding to the minimum value associated with that key.
