Incredibly off topic (but addressing an earlier issue):

My DH works for a bank... one of the big 4... and quite frequently he is asked to help in the selection of managers' assistants.
Do these positions require tertiary qualifications or were they hiring people straight from high school?

Once a person has a degree or diploma, or is 5 years out from school with work experience, i can't imagine them having their high school listed on their CV anyway.
