Amazon Enterprise Risk Management interview questions

Extremely negative experience. I was referred internally by someone who was at a networking event and asked to submit my resume. Hesitant to do so because she looked very unhappy herself. Followed up multiple times and finally emailed by recruiter asking for availability. Followed up multiple times week after and finally got phone interview scheduled and time was changed the day of scheduled interview. Manager who interviewed disagreed with every response and could not describe job role, team or anything about her role and was very defensive. Confirms the reputation that Amazon is not the best place to work for. Waste of time and most negative and unprofessional experience thus far.
