Once through the selection process however, you are in the hands of HR. I got sunk there after flying through the interview.
Not true. The candidates fate is decided immediately after you finish the interview, after lunch on day 2. After you've left for home, HR, the assessors and fleet managers from Regional and Jet sit down and go through each candidates performance.
There's no follow ups, reference checks etc. your fate is decided in that meeting.
HR's role after that meeting is to make the phone calls, they don't do any further spadework or assessing.
