Where do I begin?

Where do I begin?
Hiring Process: I was hired for a Technical Support role. I applied online went in for an interview, got the job, and had about 3 weeks before training began.
Job Offer: Competitive wages, full benefits, and full time hours.
Professionalism: I was insulted and yelled at my second day of orientation by a HR Recruiter. She said my name sounded like a disease and said it sounds like something you need a prescription for. She also yelled at me for not being on the correct page why she was going through the on boarding process. Lack of respect, and professionalism from someone of authority. This seems to a pattern with SOME not all of those in positions of power.
Training: They will offer anyone a job that can make it past the interview. Diversity is evident but there are mass amounts of people who do not meet the qualifications. They do not hire for attrition, therefore they keep unqualified individuals in the class, and people who do not respect the code of conduct or professional values.
Trainers have to deal with disrespectful adults, and those who want to learn are punished for other adults actions. They also do not seem to get the support they need from training management. My class was punished multiple times as a collective for the actions of select individuals.
Final Thoughts:
This is a good company to work for if you can make it past the training and everything that comes with it. I personally have experienced a lot of work environments and a lot of non sense but nothing of this nature.
