Four Seasons interview questions

Long extensive process that dragged out, but every person I spoke to seemed courteous and professional When I asked for feedback after interview 3, they bounced me to a generic hr rejection email, I was blindsided. Very unprofessional. I understand that you don’t always get an offer, but after 3 interviews I feel like I should be able to get feedback on why I was passed on. Extremely disappointed with the Four Seasons Brand.
