LinkedIn Software Engineer interview questions

A recruiter reached out to me on LinkedIn and set up a technical interview, which was your classic CoderPad situation. I had a second CoderPad interview, and when I was struggling, I "heard" them turn the mute button on, which honestly is a little intimidating. One of the two interviewers was very condescending throughout the entire interview and sounded annoyed when I was simply asking clarification questions before starting to code. Question wise, they were pretty easy--I just got flustered and nervous.
