First part of the process is a basic application form, followed by numerous aptitude and psychometric tests. Then you'll have to answer some work based situational questions before you can fill in the main application form. Next stage is the assessment day. You can expect lots of group tasks along with an interview and a basic science exam relating to your chosen field. Expect the process from application to starting work to take up to 12 months, particularly for graduates. Although in most cases its around 9 months.
