Grant Thornton interview questions

Applied through college job board. Recruiter asked to schedule a 30 min virtual interview. It was a phone interview. The recruiter calculated the time difference in time zones incorrectly so the interview was 2 hours later than agreed upon. The interviewer was a senior manager. They started with general personal questions and quickly moved to technical questions. After 10 minutes, I was interrupted and was given advice on how to have “conversations in general”. It did not feel like an interview at this point. The questions stopped. I had no time to talk. They spent 20 minutes giving me advice for future interviews. I felt patronized at the end.
