Hi,

After rigirous preperation and thanks to the network of individuals on this platform I have been extended an offer to join McKinsey & Company as a business analyst right out of university (undergrad level not MBA). 

The firm communicated that they would on-board us in segments over September to Decemeber.

My interview process lasted a good three months and concluded two months ago. During this time due to a number of reasons, I found my graduation would be delayed till the end of the fall semester, which means I would get my degree by December 2021 at the very latest.

This delay is not because I have a class left that I need to take but rather a final semester project that has been delayed in my case due to me switching programs in my first semester in university. In short, this project is a 'do in your own time' report which means I am entirely flexible in my timings and days.

I have offers from a couple of other top-teir companies who I have already communicated this to and they've decided to hire me nonetheless with a condition that I must provide my degree by December at the latest. However McKinsey is my dream job so naturally I am significantly more nervous about sharing this setback.

Given this reality, I understand it's important to communicate this to the firm however I would like some guidance on:

a. How to communicate this and to whom i.e. should I reach out to the partner who interviewed me and called to extend the offer or to HR.

b. The implications on my offer i.e. what is the possibility the offer will be invalidated or rescinded?

Thank you for reading this through and providing your feedback.
