Severance and unemployment, do they overlap?, software tester here

I was offered severance of 12 weeks after being let go as a software tester and I am unsure how it affects benefits. I do not usually post, so bear with me. I also wonder about the job-search requirement. How did your state treat it?

Before signing, I asked a friend who is a lawyer to look at the agreement. It was a short conversation and worth it.

Some states only count certain kinds of severance. A local workforce centre could tell me which.
