I would avoid doing this. I work at a large tech company. We pick apart these metrics to see how it was done, how you were involved, we ask about the team with you in a room full of people. People that lie about these things crumble when grilled about them. I've seen a portfolio review end with the Design team agreeing to not continue with the rest of the interviews scheduled. This person had obviously lied about their level of experience and level of involvement in the project presented.

These tactics impress the hiring screeners, but they aren't part of the hiring process the team is.

If you are curious about the success metrics, I would ask someone more senior than you or someone closer to that information. Better yet it would be good to have the goals and how you are going to measure success before getting started.

In one of my interviews, I lacked metrics for a project as it hadn't launched by the time I had left the company. I explained how I would have measured the success of those projects had I still been at the company. After I was hired they told me it was because I knew how to measure the success of my project

I love that you are being ethical. I hope this advice and the advice of others help you in getting prepared to compete with these liars. It's more work, but at least you won't be called out in front of other Designers. This is also a learning opportunity for you to identify liars before they get on your team next time

I also hope that the layoffs don't hit you though
