Meta Software Developer Internship interview questions

Codelab test was shared Two Phone Interview The interviewer was not patient enough to hear your answer. It felt like for sake the interviewer asked those questions. She asked two coding questions for which I answered perfectly fine with the most optimal solution and explained complexity, still, they didn't move forward which was quite shocking. When I asked for feedback, they didn't give any feedback about the process. As far as I know, from the interviewer's tone, she was not in a mood to interview and I felt she just wanted to talk 45 mins and finish the interview.
