NBCUniversal interview questions

I applied for this role online I was invited to an interview which we could have had on the phone as found our was a screening interview. The interviewer was 20 mins late preceded to then ask me to hold on as she has an email to send! When we finally sat down she has no interest in me had not read my CV and I never heard anything. The arrogance was unbelievable and considering was interested in working here would never make that mistake again. Appalling!
