Probably not, I think it’s rolling. Like some people actually had invites from a school before the r1 deadline which is when the bulk of applicants press the submit button. They might have some criteria maybe after the decision day where they batch based on nationality, job function, stats, or it just might be truly rolling. Maybe they do that, maybe they don’t, but i don’t think we can sort of say with any certainty
For any context, I submitted the application on 7th which was the extended deadline for r1. So pretty much as late as it gets and received an invite. I think if someone has not yet heard back from the school might be a waitlist or maybe the school is still making up their mind. I think most likely the profile would have been reviewed tho by now
Again, just speculation
