The questions vary from person to person and will depend on your pysch profile.
Agreed.
Some people they are friendly too others they give a real hard time. Had a mate leave the interview a shattered man after the grilling he copped! They make up stuff, cut you off, have a go at you, accuse you of lying, play games etc etc
Perhaps in the past, but not any more -
they want to hire you so why play games?
They also give you some standard interview questiosn, AIP, Aerodynamics, QF stuff.
Also no longer, purely behavioural now. No tech/company knowledge tested.
