I think you have gotten lots of great advice in here, but I'll throw in my .02. Definetly get some practice interviews in. There's no practice like doing the real thing. You won't find youself blacklisted by any means. Also, you have more time at 1000/100 than alot of other interviewies out there. You are definetly hireable, and you will find your groove and nail a job down. Don't underestimate how much interviewing sucks. It's stressful for anyone so don't think you're the only dude that's been turned down. If they ask you about "advanced training" just reiterate your strong points in your flying and maybe throw out some experience you've gained through instructing. Dont worry about an RJ course. You've already put plenty of cash into your ratings. Best of luck! Relax, prepare and you'll be fine.
