I have only been on the board since September, so I'm afraid I can't compare the current process to the previous one.
I can remind members that the selection advisory board is a group of nine people, chaired by the chair of the IRB. Four of the members are jointly appointed by the chair and the Minister of Citizenship, Immigration and Multiculturalism. The IRB chair himself selects the remaining four people. Of those remaining four, three are currently senior GIC appointees in the IRB, and one is a senior public servant. They're the ones who manage the whole selection process.
Then one of those people sits on each interview board, in addition to an HR consultant. There is usually a senior public servant as well. I've sat on interview boards, and my colleague here has sat on interview boards. Then we interview candidates on the basis of those six competencies; they have already been assessed on four competencies through a written process.
I can't compare it to the previous process, but I can say it is a very rigorous process that candidates go through.
