I think we have a winner, folks.
My understanding was that they wait until after the interview season is complete for the majority of candidates, so everyone can be compared equally regardless of when they submitted their app. While I agree which that in theory, it's really not fun for candidates to be in a perpetual limbo of not knowing when (or if) you'll get a decision.
I never thought I'd say this, but I wish they were more like UW lol. Tell everybody not to expect a decision until March, but give regular-ish updates that we're still in the running and give us a date to circle on the calendar in March.
