I also have absolutely no ties at all to Hawaii and still got an invitation to interview. I ended up going to my interview last month and was told exactly why I was invited. They have a point-based system in which if you accumulate a certain number of points, they invite you; non-residents need to accumulate a few more points than residents to be invited; points are given based on ties to hawaii and all other hawaii-type connections, grades, mcat scores, honors, extracurricular activites, volunteer/research...I don't recall the essays as having any merit as far as a possible means to earn points. So basically, there really isn't an "initial" screen you have to pass in order to get to the second screen. They also told me that they send out their final decisions in April, yet if you are a highly exceptional/qualified candidate, you will hear back earlier. Hope this helps
