First of all, hiring is done by departments. My group, my office, does not hire for the whole public service; we hire for ourselves. But speaking of the public service, there are various avenues. There is the post-secondary recruitment drive that the Public Service Commission is in charge of. There's also mid-career recruitment. In fact, you might be surprised to learn, as I was, that the average age of a recruit to the public service is now 35. We're drawing from mid-career as well as post-secondary populations.
Departments have their initiatives to hire from outside the public service. Often they are aided by the Public Service Commission in establishing pools of people who might come in from outside. For example, in the recent past we've tried to attract people with financial credentials because there was a shortage of professionals with that expertise, as well as auditors.
Through planning we are trying to identify our needs for the future and look at how well we are equipped to supply those needs globally.
