Action Behavior Centers - ABA Therapy for Autism Direct Support Professional (DSP) interview questions

I had one phone interview, which went well. A second in-person interview was scheduled for the following week. When I arrived for the interview I was told that the person interviewing me had an emergency and was not going to make it. They had known this for at least three days and did not text or email me that the interview was being canceled. The day after I received a form “Dear John” letter thanking me for the interview, but I was not selected. Huh ?? Total unprofessional on all levels.
