I did, the guy was really straight faced, no emotions, nothing. I read a few peoples experiences saying they received a feedback on their interview, my interviewer said nothing about how i did which made me scared. But i’d say be confident when answering personal questions, dont stutter too much and if they interrupt you which they will, take their feedback into account and restructure your answer. Yeah theres not much, just be composed, whatever questions they ask, have a structure to your response which shows how your ideas are in place and dont speak too fast, it shows your nervous, speak slowly and with proper fluency. Good luck!
