Don't really know what the applause is for but all 330 crewing is done internally. No direct entry onto the WB fleet.
MECCTI are obviously lurking on these forums. There is no upfront fees required now at the time of the sim eval and interview. All fees to be paid after joining WY in MCT. Also heads up on a technical written before the interview and sim.... FYI.
First hand info from guys who have recently gone through the assessment.
Good luck.
