Amazon Lab126 Technical Program Manager interview questions

I got referred by a friend for few positions, received a call for one of them. Hiring manager explained the interview process and also guided on the preparation. During the phone screen interview, The interviewer was not the person who was told to me will be taking the interview, so it was a slight shock as I researched a bit from LinkedIn about the proposed interviewer. Moving on, she told me that she will be taking notes and will mostly be on mute. The interview went ok, as she was on mute most of the time, I felt a little disengaged and also a little extra conscious as it was just me who switched the camera on. The questions were good and I got opportunities to speak on various aspects of my experience and some situation based scenarios.
