Superlative Group interview questions

I had a great interview with the hiring manager. When I was moved to the next step, the President proceeded to berate me based on my background and qualifications. I was warned the President was a "jerk" beforehand by an external contact of mine and I got to experience it firsthand. I didn't get the job and I am glad. I will do everything in my power to avoid and do any business with this company based on the actions of the President.
