Feeling incredibly blessed to report that I was accepted off the waitlist today (got a call around 1:45 PST)! Just wanted to report this with the intention of reassuring people that waitlist movement IS happening. I know this type of post might be stressful to those who are still waiting, but I genuinely wish the best of luck to everyone and I hope this post doesn't come across as humble-bragging. Feel free to send a message to me if you have any questions, I'll try to respond in a timely manner.
General notes for those who might be curious: interviewed in late Nov and was in decently regular contact via email letters (including a LOI).
