Thank you all for the responses! This is exactly why I posted this here.
I appreciate the recommendations and the discussions.
I went the safe route and didn’t share anything that hasn’t been released. During my interview, there was of course the HR line of questioning, where I was asked to describe 2 times I was faced with a challenge etc etc and how did you overcome? It was here that I could mention the challenge of having projects cancelled after months of work and how it can be disappointing for sure, but also how you can learn from those experiences and apply that learning moving forward.
Another one of my important things that I have learned is to be open with my manager about updating my portfolio early and often. That way it wouldn’t come as a big surprise out of no where, when I ask if I can put a project in my portfolio.
Thanks again everyone!
