Current OMS-II and student interviewer here! I interviewed the last week of March when I applied and was WLed, but was still accepted in May! Hang in there guys, interviews are still happening and there is always movement on the WL!
Can't give specifics about the WL (unfortunately don't have access), but I know first hand that things shift around a lot as people are committing to other schools. I know it's excruciatingly frustrating to wait this long, but know that people are still getting interviews, just hang in there!
Open to PMs if you need some words of encouragement or if you have any questions that I can answer. Just know that I am also studying for boards, so my response may not be super speedy.
