ViaPath Technologies Program Manager interview questions

I received an email from the recruiter requesting that I schedule an interview. I scheduled an interview with her four separate times. Each time, the recruiter failed to show up. After that, she ignored all my emails. THIS IS THE RUDEST, MOST UNPROFESSIONAL BEHAVIOR I HAVE EVER SEEN FROM A COMPANY. If this is any indication of how they treat people then I wouldn't want to be associated with them.
