In person on campus interview. After talking with the other interns, I found some interviews were 1 on 1, but a had 2 recruiters. It took about half an hour.

Usually there would be a psychometric assessment but it wasn't the case for this company you just have to apply and hand in cv. Once they decide your application is successful, you'll upload to their portal a series of online videos of you answering five questions about yourself. This is to get to know you before they offer a face to face assessment centre. Unfortunately due to high competition, I didn't qualify to the next stage and therefore I'm not sure what comes after this stage.
