Bizjets do not require you to do aerobatic training. NJE felt that aero training would be useful for the cadets (read low houred pilots) as they'll be doing a lot more visual flying/circuits in mountainous areas than if they were working for an airline.
In general, it is not a requirement for direct entry employment.
Re the JOC, do you have a MCC? That would be more useful. However, what you need to concentrate on if you haven't done so already is get a job.
