Hi MPH
EPR gauges were the round type.
Asked about FANS (not the round spinning ones), dynamic aileron (Airbus), what can Cathay offer me, why does the 747 use EPR read outs as opposed to N1 readouts.
Getting up to speed within the industry might be a good idea, ie: read through last few copies of Flight Int'l.
Also engine thrust on various ac within the fleet. Not difficult if you've done your homework. Oh yeah, also basic questions on the ac you fly frequently, so if it's a light twin then know the hydraulics for the flaps, gear etc. List is endless.
I went in with 1200 hrs TT and just over 200 on twins, in hindsight perhaps I should have waited until I had more. However, the experience was great and boosted my confidence. I had 3 airline interviews in 2 months, CX being the 1st, got the job with the 3rd one. Good luck.
