Unprofessional

Recently, I had a chance to interview for a new grad role in MAANGs (phone screen). At first it was scheduled on 18th March, 2026 (2 interviews on same day). I entered the first interview meeting link 5 minutes before, waited for 15 minutes, noone showed up. I mailed my recruiter to reschedule and same thing happened for the second interview. They rescheduled it to today (25th March, 2026). First round started on time. I kinda messed up the round (coded pretty slow on a medium design problem). Then the second round started on time, the interviewer showed up and it was going pretty smooth but he dropped off abruptly and didn't join back. I have reached out to recruiter, but honestly this is kind of unprofessional especially from a top MAANG. Kinda makes me wonder is it normal or am I overreacting?
