I'm from Italy, applied in R2.
This was my approach:
- thank you email and quick career update after receiving the WL offer (end of March);
- submitted the video, addressing what I believed was a weak spot in my application;
- updated resume (just a slight update with recent achievements (uploaded onto the portal last week);
- also last week, I sent a second email to adcom, confirming my interest in Booth and giving them a few reason why I would accept an offer despite the current COVID situation. In the same email I mentioned I updated my resume and quickly explained the rationale of my video.
Good luck to everyone still waiting!
