MDE Installations interview questions

Very Unprofessional. They sent me an email for a phone interview. I scheduled a time. They never called. Sent a polite email . No response. I am a highly trained candidate, I got frustrated and went and applied at another store. Wondering with the unprofessionalism if they are getting ready to go out of business. It is never okay to disrespect people. I can only imagine if they do this, what kind of company they would be like to work for. Their name used to be something special, now there behavior speaks for itself.
