Hey,
I telephoned and spoke to a lady from GAPAN to get feedback. She went through the feedback from my application with me and highlighted them as the 2 reasons why I didnt get an interview. Also, they score you out of 10 on the "essay questions" as she call it and said I scored 10/10 on the first part but not so good 6/10 on the second part (recent achievement part).
Telephone for some feedback if you didnt get an interview. The lady was extremely helpful and very kind.
