Equitable Advisors Human Resources interview questions

Applied through Career Services at my school. The HR person contacted me for an interview on a Friday Morning. I get there and the person who was supposed to interview me was no where to be found. They looked around for her and they found out she took the day off. They weren't prepared for me. I got interviewed by the Executive Assistant and she was not really familiar with the position, in my opinion. I got no apology and I never followed up because I believe they were unprofessional.
