Madison Performance Group Technical Project Manager/Business Analyst interview questions

I applied via LinkedIn and few days later I was approached if I am able to come for an in-person interview. We scheduled the interview. Person who interview me was very distant and cold, like there was no chemistry between us. I was asked to provide some documents from past projects but I am bound by NDA (Non-Disclosure Agreement) and I could not. I guess then my candidacy went south and I was not chosen for the next round.
