Date of interview: 9/30/2024

Question: I am now in the post-interview pre-decision stage. I received a promotion from work (MBB strategy consulting) two days ago and am considering writing a few paragraphs and uploading the doc to the 'New Information' section of the portal (and maybe also an email to AdComs?).
Has anyone done this before? How should I structure the document? What is advised to be included?
FYI: My responsibilities do not change much, just a more standalone, senior strategy consultant.
I would appreciate any advice, thank you so much!
