I'll also add, they appear to have a really excellent Career Services office! I've heard great things from students about Career Services and they also provided me with very detailed, extensive information on recent grads' employment outcomes and salaries, something I have not received from any other school.
Just like everyone else, I'm frustrated Columbia isn't going faster with admissions/aid, but I think a lot of people are forgetting how many other schools are being just as slow. Personally, I have not heard a peep from BU or Brown (other than a rather frustrating experience of them having issues with my FAFSA), despite applying in early November. I have not yet received any word of aid from several other schools to which I've been accepted, same as Columbia. The HSPH admissions office was even quite rude on the few occasions I contacted them prior to applying. I think the frustration with Columbia is totally understandable (especially for that yikes false admissions glitch), but if we are going to be upset with them, I feel like we should be just as frustrated with other schools too haha
