From my knowledge, people who got interviews were the top picks from the applicant pool. I've also looked at the forums from all past years and it seems they will start sending out denials within the next month. However, there will be some put on a "waitlist" until some of the first wave of acceptances start responding, either accepting or rejecting UNH's offers. So, some who do not hear back at all until mid April should assume they are on a "waitlist" and they will be accepted or rejected based on the first waves responses to admissions.
I think that makes the most sense! Good luck!
