The interview was mainly about criticism of my school projects back then, and I was a fresh grad at that time. They asked me to propose a theme for an assignment but ended up never replied my email. Not sure if the person who interviewed me is still there, but it really scared me for a few years. I did send out my portfolio prior to that face-to-face interview, if my work is that bad, why would you waste both yours and my time to just ask me down to criticise me and never replied my assignment email.
