The first couple of people from the team who interviewed me were excellent and polite. However, when I reached the final interview with the hiring manager, they seemed distracted or preoccupied with other work. They were not listening from the very beginning of the interview, even before I had started speaking. I'm not sure if they were having an off day.

At the beginning of the coding question, I suggested two possible solutions or good design choices, which the interviewer did not hear. I felt like I was talking to myself.

At the time, I forged ahead with one of my two approaches. Near the end of the interview, the hiring manager suddenly told me I should have used the other approach and had not even heard me suggest it prior. I repeatedly had to remind the hiring manager what line of code I was referring to, as they would stop paying attention for minutes at a time and had no idea what I was doing.
