ok, been there, got the t-shirt and wrote the book. It sucks big time.
Now, you have to really look hard at yourself to make sure you have gotten over it. Prepare answers to the possible questions you might be asked about the "failure" in an interview. Don't hide it, the industry is too small. The future operators will want to be sure that you have learned from it and have taken steps to correct it or fill in the experience gaps.
So, now it is time to walk before you run. If you can, find a type that is a bit easier to fly and get some time up on it. Easier said than done I know.
Have you revalidated your IR? If not, do so, it will help your confidence.
Target operators that are likely to take you on rather than just blanket mailing.
Be prepared to travel to meet these operators.
