I learned about this opportunity through a recruiter. The product was interesting and the tech stack seemed good, so I wanted to give it a try.

The first step was a phone screen with a senior engineer.

Initially, the engineer seemed nice and professional. However, after a few minutes, he began nitpicking a typo on my resume. It was unusual. He focused on that for a while and made sure his point was clear. The interaction became uncomfortable.

After this, we chatted briefly about my current work and projects, and then we moved on to the coding portion. He insisted that I conduct the interview in Java. I stated that I wasn't comfortable with it, as I don't use Java in my current role. His response was, "It's there in your resume." I couldn't believe it. I had a bad feeling about the rest of the interview. He said he would help me. I worked through a simple linked list problem, but this experience threw me off balance, and I couldn't maintain my usual pace.

I'm writing this to inform others that you will occasionally encounter interviewers like this. If you come across someone who tries to make you uncomfortable, it's best not to proceed with the interview, as it likely won't end well for you.

Given an array of linked list nodes and some root and non-root nodes, find the non-root nodes.
