Since I forgot sdn is semi neurotic (whoops) and I've had time to process, I'll just share the broad strokes of insight here (with special thanks to f_my_drag_right and Force Healer who interviewed at Seattle for a bit more of their insight):
1) Seattle and Spokane have slightly different sets of questions. Spokane on the whole tends to be nerve-wracking but a bit more conversational compared to Seattle (which is generally nerve wracking). For Spokane, the health policy MAY NOT be as prevalent to know (but you should still know) vs. Seattle where it may be essential to know it seems.
As for why I think I got rejected, I think it was a combination of various factors. One being the bit more random (and conversational like) questions that UW had, not being as prepared as I should (a bit rusty in interviewing which led to definitely hesitating/ tangents on questions I should've known better how to answer) and trying to be what I thought UW wanted rather than being myself (which led to a bit of confusion in answers and lack of genuineness)
For advice: 1) Know why you're interviewing for the campus you're interviewing for and if you said no preference, don't say that you initially did that (I did which probably was a dumb move in hindsight). 2) Know what makes you specifically unique as the class itself is large, but the cohorts themselves are small and they want someone who can be a unique person in their class. 3) Remember to be genuine and confident in yourself. Don't try to convince them you're something you're not / you have knowledge in something you don't since it won't go well for you. 4) Know your health policy cuz there's a high shot this comes up in some shape or form. and 5) Remember to breathe and be ok with the fact that your interviewers/ EXCOM will not necessarily converse with you or have humorous laughs with you, but they still like your answers.
Good luck y'all 🙂
