assessment split into 4 parts.
tech multiple choice questions, 30 questions/30mins. questions are straight forward. I would assume pass mark is high, at least 85-90%. They have several papers so question will be different for candidates, but all are same level. Few questions on company itself, some basic aviation knowledge questions, ATPL, and last comes some reasoning questions.
Group exercise is straight forward, you need to participate and be involved but not bossy etc.... as per usual.
lunch break, at least half of the people will be send home after lunch break. standard extremely high! or at least they say so!
HR interview usually with airline captain and FO or IAGO HR personnel.
Scenario based interview is again with airline captain and FO etc..
Followed success on day one, sim assessment! Good Luck, hope that helped.
