Infegy Client Success Manager interview questions

I received a meeting cancellation notice, 7 minutes prior to my scheduled interview time. I received a second email from the leader that was going to be interviewing me, stating they had filled the position. Cancelling an interview on such short notice and then informing me that the position has been filled is unprofessional and inconsiderate. This just provided me valuable insight into the company's culture and how they may treat their employees because a company that doesn't show basic respect and consideration for potential employees might not be the best place to work.
