Applied online through the relevant website, received a letter/email inviting me to a selection day. This consisted of aptitude tests such as English, Maths and Problem solving. There was then a group exercise to gauge teamwork, followed by a hands-on practical aptitude test. Upon success of this stage, you are then invited back for an interview, one-on-one and in-person with a manager. After the interview, it was a matter of weeks before I had an initial job offer over the phone, in which I accepted, and then started the apprenticeship.
