Creative Resources interview questions

My experience with Creative Resources can be described as nothing other than a fiasco. I was contacted by a company recruiter about this position and was asked for an interview. Given my background and resume, I was overqualified for the position, but I was still grateful for the opportunity. I went through a total of 4 interviews with Russell Poucher and his team. I believed them to be pleasant as I breezed through them, but everything changed once they sent the offer letter. First of all, the offer letter had a much lower salary than the listing as well as no benefits whatsoever until 90 days. I believed my value and time to be more important than the pitiful offer they made, so I requested negotiations about the offer. I discussed with Russell Poucher for half an hour to argue my case to reach a mutually beneficial agreement for a revised offer letter, The meeting ended with Russell saying he'll "think it over". The very next day, Russell denied my request, but the worst part came next. I replied to his email about if the initial offer was still available, but he rescinded the offer with no explanation given whatsoever, I politely asked for any feedback on my interview process and some explanation for the reasoning of the job offer being retracted. Russell displayed such a drastic change in tone and demeanor after our civil negotiations of the job offer. Initially, he was pleasant to meet with. He was approachable and responsive to the communications I sent. I am now left dumbfounded about how this man I once held in high regard has refused to acknowledge my request for feedback or explain his decision. When writing this, there has been complete silence from Russell's end for 5 days. I followed up with an email yesterday and called the office today. Instead of being met with appreciation for my interest in the role, I was instead rudely denied and told that "I am not owed an explanation whatsoever", despite driving out to 2 on-site interviews and 3 online meetings. I have never been so insulted and offended by a company's gross disregard for extending basic human empathy. I would not recommend anyone to work or even interview with this company.
