Master of Arts (M.A.) in Global Communication by USC and a Master of Science (MSc) in Global Media

Hi,
I’m applying to Master of Arts (M.A.) in Global Communication by USC and a Master of Science (MSc) in Global Media and Communications by the LSE. However both schools do not have interviews as part of their process. Should I offer to interview any how?
I live in Brazil and I’m willing to travel to L.A. and London to interview but I don’t know if this will help.
