If this is helpful to anyone, I received a rejection email from GW GH DrPH this morning. I interviewed back in January and thought it went pretty well.
JHU HBS has a lot going on. The HoD is leaving to be dean at Albany...same as 1/2 other professors. Might explain why they're slow with the review process.
Same status, though I did have faculty asking me when I'd hear back from some other school they wrote me a reference for...they have no idea I know they are on the admission committee 0_0 (which is why I didn't ask them to write me a SoPHAS reference in the first place).
I interviewed with GWU DrPH GH last week of Jan. No updates though they did say expect mail in 4 weeks. Also waiting on JHU customized DrPH - the application status has been "sent for review" for several weeks though an admission committee member asked me via email when I was expecting to hear back from my other schools (does that have anything to do with anything?).
