I applied online in 2013. No CV / Cover letter submission was required which was nice. The first stages were online tests (I cannot remember the details but it was around behavioural situations and how one would react in certain situations to see if your personality/character matches the company requirement) . Then it was the assessment centre - they sponsor flights and hotel ( I flew in from an European country). The assessment centre was fairly standard 1) Group activity 2) 1:1 interview 3) Competency test 4) Role play

Interview consisted of competency questions on their business behaviours. 4 business behaviours were chosen and each had 3-4 competency questions associated with them. There were a total of 13 competency questions. The interviewer also asked about past work experience, university experience, motivation and all other general interview questions. Interview lasted just over 60 minutes.
