Pay for good interview prep. FAPA and emerald coast have good reviews. Good prep includes practice and specific intel on what to expect. Don’t blow this by being a cheapskate. I know people say “just go in and be yourself.” Those people are 100% full of ****. Legacy interviews are formal and require good preparation. The interviewers want to see that you are prepared. A few hundred bucks now for prep can equate to a few million dollar career.

Aviation interviews is a subscription site with good reviews. I’d subscribe to it also-but there is no substitute for practicing real interview situations with real people.
