Easy back when you went to a careers office not sure its still as easy now that it is all done online. I hear the process is now pretty long

The interview was in the form of a weekend away, running around and being shouted at. You have to pass the fitness test, a medical, a short interview and some little command tasks. Oh and there's an online aptitude test.
