My group went through a few weeks ago on the F/O Freighter program. The HR questions were the predictable ones about why you want to work for Cathay etc, as well as numerous questions about the career choices you have made so far and the positive traits you will bring to Cathay.
Most of us were also asked a fair number of "Cathay" questions.
When did we get our first 707? 747-200? What is our latest city pair? Where to we fly in Europe? in Australia? What is the difference between long haul and short haul?
The tech questions were along the lines of what we expected and prepared for for the past 4 months, plus there was an emphasis on Winter operation/slippery runway/windshear type questions.
Hope this helps.
Good luck.
