Really easy and straightforward. Started with an application letter, resume and questions where you had to specify what makes you a good PASS Leader. Extremely important to stress that you have gone to PASS in the past (they do check up on how many times you went as a student) and that you explain that PASS is very different from tutoring.

Reasonably quick process, sent in application and received email back shortly afterwards with interview. Interview itself was reasonably quick and laidback. Questions were quite easy and straight forward, I think they just want a better look into who you are as an applicant.
