It was quite easy, but some people at comms mess you around which is not acceptable.
They prioritize some guards over others and sometimes just lie in your face.
All in all i would say the interview was average and quite fast.
I applied through a staffing agency. I interviewed at Cordant Services (Aberdeen, Scotland) in July 2015
Interview
meet a cordant rep in public or get into his car at a pre-arranged point. bring realative documents , passport,work history,etc important -s.i.a. badge, they seemed really keen to hire me. so just be yourself.
