HR listen to the hiring manager

"She has one concern now , if she got the final offer from the hiring manager, could the company's HR reject the offer because she got that below expectation three years ago?"
-- HR listen to the hiring manager;
-- Company B has no way to know the good or bad rating she got in company A unless she tell company B.
-- There is nothing to worry about it.
-- You are so------ nice to help your friend! Thanks a lot!
