Must say, my experience with them was top notch.
From email of interest to Ottawa, to assessment in Canada was around 3 months, and job offer was during the week I was there, with a number of start dates and different geography to choose from.
Elected to stay put after all of it, but the point is they seemed very competent and helpful throughout the exercise. This all occured in Mid'02 - not sure of they have the same demand now?
(Three colleagues from 'down here' did take up the offer - I believe their experience was similarly expeditious. )
