It doesnt really, it depends on the field of bussiness, but the times I been asked to look over CVs/ do interviews (when my boss is on vacation/too lazy to handle that many same time), I focused way more on the interview part. CV is just a general ballpark, and window to get interview, but however you dazzled your way with CV to get ahead for interview chance, if you arent as prepared for the latter the CV didnt ultimately matter much.
