I received a message from a LinkedIn recruiter on LinkedIn. After a few days, I was able to schedule the phone screen.

I had the phone screen, but it did not go so well. The question was a LeetCode problem that seemed simple but was actually tricky. It is classified as "Easy" on LeetCode, but I would call it "Medium".

I coded up my idea, and the interviewer said I was on the right track. However, unexpectedly, the interviewer ended the interview and hung up without giving any reason. I felt that was incredibly rude.

Afterwards, the recruiter informed me that I had been rejected. I know it doesn't help, but I provided the recruiter with the answers to the LeetCode questions asked after the interview anyway.

I was told I could not reapply for a year due to only one LeetCode question. It was a terrible interview experience.

A LeetCode Easy question that appears on LinkedIn's list of questions on LeetCode. These are the ones you probably won't practice since they are "Easy" and low frequency.
