Aggreko Project Manager interview questions

Painful. In all honesty I wasn't prepared for the interview. I wasn't in a great state of mind due to a family bereavement. But two of the questions I was present with by the interviewer are the reason for this review. What is PRINCE2? I was asked this question by a Project Director........ Do you not have a degree? No I don't have a degree. I've had a vetting call with your HR Manager who has read through my CV and put it through to you for review.
