There are no recent interview "gouges" available. If you look back on Pprune you will find somoe of the old ones as well as on aviationinterviews.com. I would imagine the pattern is similar. Three books seem to be making the list each time:
1. Ace the Technical Interview Gary Bristow
2. Handling the big Jets. Davies
3. Emirates Interview by Capt X,Y, Z.
The other stuff you really cannot prepare for (MMPI etc). Be obviously familiar with the A/C you currently fly and brush up on raw data flying. I am sure others here will have additional information to add.
