Online application followed by online tests including situational and also maths which are timed so ensure you are prepared and somewhere quiet. Once you have done these you will be notified if you are to go to an assessment day which I did. On the day there were about 42 people all ages and a good crowd. I would treat the time you wait in the canteen as part of the test Nd ensure you mingle a few people I watched came in and sat on there own and even after induction. At the second break some were still on there own and these guys didn't get through later on. You do 3 group exercises ( there is no right answer it is all about teamwork and participation). After a lunch break you come back and they call out names about 26 these all went to another room. We were then told we had passed X factor style where they start off as if you have failed. You then go to a 1-1 interview
