M Culinary Concepts interview questions

Didn't have the chance to interview with them. I applied for the position through their website, then received an email to schedule a phone interview. The hour before the scheduled call, I received an email from that they were cancelling the phone interview but that they would reach out again as soon as possible to reschedule. I received no explanation for the cancellation and I've followed up since then to reschedule with no response. Very unprofessional.
