I was recruited via LinkedIn after applying on their website. I had a phone call with the recruiter and then a video call with the hiring manager.

After that, I was asked to do a video interview with their researcher, focusing on ML fundamentals.

The interviewer joined the call five minutes late and did not apologize. He started by asking how I would create a parse tree. I replied that I didn't know the specifics of a parse tree beyond vaguely recalling what it is. He then buried his head in his hands and let out an audible sigh.

Next, he asked what a way is to check distribution comparisons of language models with information theory.

Afterwards, he asked me to create a podcast search, even though I have no information retrieval experience listed on my resume and it wasn't related to the role I was interviewing for.

He ignored my clarifying questions without responding, gave contradictions, and was rude throughout.

After this interview, I didn't hear back from the recruiter, even after a follow-up two weeks later. I am extremely disappointed in the time I wasted talking with the team and the lack of professionalism.

How to compare language models using information theory, create a parse tree, and design podcast search using only transcripts. (Later contradicted himself, asking why I didn't use metadata features when he had previously stated I could not.)
