Project Deep Dive Interview

Hi Team,

I have an full loop coming up and one of the 4 rounds that doesn't seem standard for big tech loops. It is the Project Deep Dive.

I have suspicions on how to prepare: aka have a strong "tell me about a project you are proud of" story, and be able to explain it in excalidraw.

So for mid level, my guess on how to be successful in this round is to go into detail about the edge cases of the project I worked on, and how I drove the solutions for them.

Is anyone here familiar with giving this interview type and if I am on the right track in terms of being able to give the right signals?
