do you mean RA offers are sent 'FROM POIs'? Are POIs the people that will send intl students offers? Just out of curiosity, did coordinator or who sent the rotation offers?
I definitely know much people who don't have interviews received rejections, but there also seems to be some people who spoke to POIs that also received rej on the results posting page.
I don't know how you feel like the interview, but for me, the interviewing profs are more like to evaluate me instead of trying to evaluate whether I'm fit for their lab research? The profs that interviewed me are my top 3 of the form I filled out, and also my top 3 POIs in the application.
Does offer generally come first or not before deciding upon whether to do rotation or direct admit? Or will this fact affect whether you're admitted or not? BTW, anyone has attended coffee hour panel?
