Callback the next day, easy phone interview where the owner explained the job requirements and training program. Was a max of 10-15 minutes with room for questions at the end

Rarely have I interviewed with a company this rude. Out of the blue he called me for an impromptu interview. Started as normal, asking me about myself and stuff that was on my resume. Since the interview came out of nowhere, I didn't have the answers about the company or the position I had applied to (out of the many daily). At which point he started asking me less about myself and about how little I prepare for the surprise interview and how poor a job I am doing in looking for work. I have had interviewers give me constructive advice, but he was demeaning. He still wanted to keep "interviewing", but after 17 min I just flat out told him that I am ending this interview. I have never had to do that. Looking at the reviews of the company, I just dodged a bullet.
