We all signed confidentiality forms so technically not allowed to say much (not even the format). But I found it less stressful than an average MMI (have nothing to compare it to) but maybe I got lucky and had nice interviewers. Some questions felt easier to answer than others, but none felt impossible. Didn’t seem like they were trying to “get you” or trick you.
There’s a sample schedule (although not completely accurate) on the portal, and I found some good advice from the SDN thread last year abt what to expect kinda.
As a note, GCSOM used to do traditional rather than MMI and just switched a few years ago, so the SDN interview feedback/questions I think were more outdated/for the previous format. Good to look at but I don’t think anyone would be posting the actual Q’s there. (noticed this before I knew anything abt the interview so this isn’t post II advice or anything)
