Labatt Food Service Software Development Programmer interview questions

The most inappropriate interview experience ever!! It started with me applying online and getting a reply not later than a week, to schedule an interview. The first interview was a Skype interview for one hour. Half of the interview was behavioral and half based on technical questions regarding the experience and projects on my resume. Sounds fine right!! But.. As soon as the interview started the interviewer YAWNED!!! He tried to control it but later came out 2-3 times again and he did not even bother to apologize or excuse himself.May it be a late afternoon interview or he was extremely tired, no reason justifies putting a candidate down like that. I still gathered myself and was trying to make the conversation interesting. But how do I do this if the interview yawned even before me answering to his first question and with him being into his computer typing notes for most of the time rather than listening or looking at me. Extremely Unprofessional and Rude is what I would say.
