From my experiences, Recruitment Centres are extremely unhelpful and useless in many ways. I apologize in advance, but you never receive callbacks and the information you actually do get out of them is often incorrect. This is just my experiences.
I learnt that if you truly want to know something, you have to actively look for it yourself. Forums, official websites, etc. It's hard to work with the Recruiting Centre, but if you want in the CF that badly, you have to just tolerate it and wade through it.
Note: No offense to anybody here who is a CF recruiter. I may have just been unlucky, but many people I've spoken to have had similar experiences. My comments are based on my experiences only.
