Artie is correct. Recruitment generally involves group exercise, psyco tests (not sure about the type rated for this one) and the usual 2 to 1 interview about aspirations, experiences, base preference etc.
If you do not get the base you want, it's pretty much guaranteed that you will after 12 months.
It is a nice place to work and things have improved over the past few years or so. 70% offered 100% at the end of summer etc, I guess it all depends on expansion. As Artie says the rumour mill is expansion. I guess we will all have to see.
