My interviewer was very unprofessional.

The interviewer started late. The interview was supposed to be over video, but she called me on my phone. We then had to switch to video, which led to some technical difficulties and wasted about 10 minutes.

I solved the problem she gave me. I ran my solution myself after the interview, and it was correct. During the interview, I even caught edge cases that the interviewer didn't catch.

While I was explaining my solution, she kept interrupting and made snide and rude comments about my approach. At the end, she awkwardly laughed, as if I wasn't going to get the job and she didn't know what to say. She then said, "We are out of time, bye," and hung up abruptly.

I understand Google is a huge company that expects immediate perfection, but this was really unfair. I expressed my feelings to the two recruiters I had. They both ignored what I said, and I was rejected from the job.
