Fired without notice - Design Consultant System Pavers Employee Review

I was hired for SP and I spent 50 hour work weeks studying to get through their virtual training class. They would keep me in class for 7 hours a day then tell me over and over I was not where they wanted me to be in learning the material. (how was I supposed to memorize a presentation when they had me in class half the day?) They would pep talk each student one by one, after the quiz the next morning. Every few minutes they would ask for a physical thumbs up to show we were engaged. This got old real fast. After I finished the training class my manager called me up and fired me without hesitation. He said the trainers didn't like me. One of them went behind my back to my manager. Not once did the trainers say anything to me that would have made me think I was disliked. I was shocked to say the least. Completely blindsided, I did not see this coming. Looking back, I think it was because I left a poor review, on the feedback card, expressing how I thought the training class could have been better if they gave us more time to study on our own instead of having us read the presentation over and over as a group. I have a family and I made a big life change to work for System Pavers. I was treated so poorly. I hope no one else goes through what I went through.
