Aviation interviews!
It’s all you need. Pay the fee and study the gouge.
Maybe Shepard Air depending on if the company you interview with gives a written.
Not to sound like s shill but Aviation Interviews is worth the cost. I was out of aviation for 8 years and studied the technical questions as well as brushed up on the HR stuff. Got the job!
Can’t help you with PSP as I’m based in NY.
Good luck!
