My technical phone screen with an engineer was as far as I got. It's intended to be a "pair programming" session, but I'll just say it didn't feel very collaborative.

The first layer of the interview was an LC easy/medium style problem. Once I got a working solution for that, the engineer added a second layer of complexity.

I described my approach, but he seemed resistant to it. He did not clearly articulate what the problem was, so I couldn't tell if he actually saw a flaw or was testing my ability to defend my decisions.

Either way, his pushback threw me off, and maybe that was enough for a rejection.

I tried to explore his reasons more to see if I should consider a different approach (trying to be collaborative), but perhaps this came off as indecisive.

I did not get any feedback on what I should do differently, and I couldn't think of anything on my own, so I decided to go with my idea. I ran out of time implementing it.

LC easy/medium, not too difficult.
