I interviewed last fall.
What aircraft does Cathay operate?
What engines does the A330 have?
And lots of questions about aerodynamics. I would also practice describing your career so far.
In the HR interview they asked.
How did you pay for your flight training?
What is your greatest strenght?
How do you feel about flying 8-12 hr flights?
The gauge is accurate. I would just not spend the time to learn specific systems on Cathay aircraft. They do not expect you to know that.
Good Luck
