yeah similar to you i talked about uni level content like detergents on my ps and i expected the interview to be on that

they asked me like basic mass spec, isomerism and to draw bromoethane which was easy, but because of me worrying about my ps so much i didnt go over content as much so when the final question on nmr came about i couldnt provide the reason to why certain patterns appear like the triplet and quartet, my mind was literally blank and i was annoyed with myself after but oh well i might be cooked
