I was at Flybe before and can say that we had a huge mix of people join. They would be quite forgiving and provide extra training. One person failed line training twice. Third strike and he was out sadly. 10 years FI experience but he just wasn’t up to commercial flying. He could fly the aircraft fine but as a crew member apparently he was dangerous. I struggled with my training. If I did it again I would do a better MCC but then everyone I spoke to says the first TR is always the hardest.
Best bets for you would be RYR/WIZZ or network like hell for a private jet job. I know many contacts who went in as low hours into private jet market but all had major contacts.
