Amc  

"You want to have something lined up instead of waiting for everyone else to jump ship all at once."

So you are already quitting but you are going to tell your future employer you can't start until November, which is three months away. Of course, your new employer will be quite aware you are screwing over AMC to collect a measly 10 grand. Maybe they won't care, maybe they will?

The training process and onboarding is what takes the time, not the hiring process. From the minute you apply, you should an  an offer letter and BE HIRED within a week or two. If not officially hired, maybe you can go to onboarding and training while you still work for AMC! Good luck with the timing so you can collect the 15 and get the job you really want. I'm sure the job will stay open for you and good luck with putting those "finishing touches" on your resume!

Brilliant plan.
