Big 4 erk.... i have experience with PWC where they give career talk in my college, so my tax lecturer ask me and my fren to go to the talk. actually, my fren and i have lazy to go but since the lecturer invite us, so we go la... then before we enter the main hall suddenly a chinese ah moi, maybe the PWC staff asked us about our cgpa and only 3 pointer above can enter... then my fren and i laughed like mad, it just a talk for god sake.. pity the student who got less than 3, because they can't enter and even to smell the PWC ah moi also cant.. hahaha...
