Omni will tell you their training is characterized as drinking from a fire hose, and their not wrong. However whats not mentioned is there is a huge disconnect between ground school and simulator; ground does little to prepare you for the sim, and that is why majority of candidates have problems. For example, the sim instructor expect everyone to have everything memorized; flows, profiles,etc, for both seats day one. In addition, If you don't know how to program/run the box day one you're, well, pretty much screwed.

Simulator training isn't so much training but rather a continuous evaluation.

Hope this helps any current and would be candidates.
