Application Submit - (shortlisted) - online assessment - (shortlisted) - face to face interview - final selection. The assessment can be fairly difficult, you are shown a number of letter or number sequences and out of a list of 5 very similar ones, you have to find the right one. You have only a few seconds to find it and the sequences get longer.

Firstly, there was an online application, then psychometric testing and then an interview, The interview was very laid back and involved conductor manager and a trainer. I received a call back about a week later.
