Thanks for the information guys.
The assessment day was very pleasant. CTC do you really put you at ease.
The interview was very straight forward. You must know about the company as if you don't, you won't pass. Expect competency based questions asking for examples of the skills and attributes of a pilot. Questions would be on the line of teamwork, leadership, flexibility, adaptability, pressure and handling.
Technical questions are also asked but not always.
I hope the above helps and good luck.
