As soon as you enter, you are given a number that is used to evaluate you; you are being evaluated from the moment you enter the room. The first part is the skills carousel part where you have to show your leadership skills with a group of people. Next is the interview and it was not bad. If you didn't shine during the first part the interview is your only chance. Overall it was very competitive with lots of people so make sure you show them everything you've got.

My school posts summer job postings for students to apply to. I applied from there and got an interview. The interviewers go the school where they interviewed the interviewees. Should your time slot be during class, you were able to ask for leave from the teacher in contact with the interviewers
