Four Directions interview questions

Nobody interviewed me. I sat in the conference room for 1 hour. Then a staff came in and said they are too busy to do an interview. Didn't even think to talk to me before letting me go. Promised to re-arrange the interview but never did. A complete waste of my time. Very rude

2 stages interviews involved relaxed conversations around technical topics and educational / professional experiences. Also common questions such as expectation, future vision, etc. The conversations were enjoyable and the interviewers present positive responds without any kind of disrespect. No skills tests, quizzes, or brain teasers, at all.
