Applied via agency and was sent the online tests ( numeracy and verbal ) within a week. After completion took about 2 weeks for a reply that i was sucessful and that i was invited to attend the assessment centre. Had about three weeks prep for this, i was sent an email telling me what to expect of the day. It was only about 3 hours long and it included a behavioural interview and a technical interview ( did not have to repeat the tests ). Behavioural interview was just to find out about your self, also a few competancy questions like about team work and pressure etc. nothing to stressful. The technical interview was more around your current role, experience, health and safety and some circuit diagrams where you have to identify symbols etc. I was told within three hours that i had passed the assessment centre and that i was invited to a trade test stage which was in coventry and a full day of tests. This is a challange to find out what you know and dont. ( There isn't much info on this stage and i think its role specific but there is practical and written tests). I have now been waiting for two weeks for an answer. I was told it would be a few weeks.
