chunkofrocks there's 2 parts, a group interview and an individual interview
for the group interview i'm pretty sure they give you some type of scenario that you and the group have to solve. idk the specifics but i've heard it's stuff like "if you're on a sinking ship and there's an island nearby pick 5 out of the 15 items we've listed to take with you." and then you discuss what items to get with the group. don't be too introverted but don't be overly dominant as well
for the individual interview they ask you one on one questions about science and the school in general, it varies from person to person. there's loads of practice questions on quizlet (just search up jmss and you'll get interview practice questions). basically just show your passion for science and STEM in general and try not to make fake claims (e.g. if they ask you if you like astronomy and if you don't like it, dont say "yea i love astronomy sosooso much" because they're gonna ask you about it and it's not a good look if you don't know much about it). for the cv try and show that you have a life outside of academics while balancing how you prioritise studies as well. here's an example resume https://www.scribd.com/document/422596757/JMSS-Resume-by-Shyam-Mahendra
i hope this helps!
