I was contacted by a recruiter from LinkedIn and asked to apply.

I had a phone interview with someone different than the person who contacted me. The interviewer was not prepared for the interview. They hadn't read my resume before the call and didn't ask about my interests.

I applied for one role but was pushed to interview for another. I was pushed to interview for a manager's role, yet they asked no questions about managing teams or resources.

I had to implement a b-tree on the fly, which was fine. The dev interviewer wasn't prepared either. Just a strange experience.

Can you implement an insert into a B-tree?
