Cisco PM interview questions

Interview scheduling took 3 weeks to finalize. Schedule even changed after confirmation email came as interviewer schedule kept changing. Interview was with 2 managers who seemed totally disinterested from the very beginning. Flow of interview was all over the place and was not even asked any important questions especially in terms of experience or work related questions (have you done this before?, etc.) Whole interview felt like they wanted to end it asap, and reluctantly asked more questions as it was "too early" Did not pass interview as Japanese was deemed not fluent enough even though whole interview was conducted in Japanese with no communication issues. Was also told that I did not have sufficient relevant work experience despite interviewers not asking a single question on past experience. Very unprofessional interviewers.
