I had the 'call' for the cleaning job and am now a swimmer in the 'pool' ('pit'?). The selection day started with a talk from the Director of Cleaning on how we were lucky to be selected for interview as there were thousands of applicants for the cleaning jobs. Then we had a psychometric testing session, a group task followed by an interview with an HR bod and one of the cleaners. The final part was an interview with a psychiatrist which goes over your childhood etc and silly family questions e.g. what does your mother do for a living
