Cancer Genetics interview questions

The interviewer was extremely rude. To start with, they forgot to schedule an interview after I submitted my availability. I sent a follow-up email and they scheduled it the very next day. After few hours they asked me if we could reschedule to a later time. The next day, they joined the interview late and asked me to tell them about myself. After I finished my answer they asked if I could start working next month if offered the position. I said I could start in 2 months after I graduate. They replied, "Oh, we are looking for an immediate hire, thank you for your time", AND HUNG UP.
