I would say the appointments process is a rigorous one at the moment. The people who apply on the GIC side, first, they're subject to a paper screen, and then they write a written test that is five hours long, divided into two parts. Then they're subject to an interview to look at behavioural competencies, and that includes things like cultural sensitivity and judgment, and finally, if they pass the interview, they're subject to reference checks.
On the GIC side, for every 10 applicants, one qualifies, and then the number who are appointed from within that pool is yet smaller. On the public service side, I would say it's an equally rigorous process at the moment, and the ratio of qualifications there is about the same. So roughly speaking, for every 10 applicants, there's one who makes it through.
