1-2 weeks of systems class - learning how the airplane works, mechanically

1-2 weeks of procedures - learning the preflight, inflight, and post flight duties, including "flows"

1-2 weeks of maneuvers, which is the hands-on flying in the sim, and emergency procedures.

1-2 weeks of LOE - simulates "normal" flights but with abnormal issues and emergencies.

each phase will conclude with a test or sim evaluation.

Additionally, the first couple weeks or so at the company is new hire orientation, learning about the company operating procedures (AOM), etc. (get your ID card, sign up for direct deposit, health insurance)

The key is to have a positive attitude, study, and come to class/sim prepared

Difficulty depends on your abilities. Some don't make it. Most do but find it a "fire hose" effect. Plan on giving 100% and you should do fine. I have been thru numerous Air Force flight programs, and found 121 training to be equally challenging but faster paced.
