This topic was started in another thread only a few days ago... Various figures have been thrown around... such numbers like 400+ per year to 200 per year. They are all massive numbers so not sure how credible any of them are really.
If these large numbers are true, what would be interesting to know is how peple are shaping up in the psych tests. With the current demand are they taking people that they wouldn'y have looked at several years ago or is the psych test just a formality these days?
