I want to be working for one of the big four companies, do you think low university grade may influence on?

Question

the decision not to hire me

i mean low average grade

Answer 1

Well, yes, low grades would hurt your chances of getting hired. When you are just out of college, grades are one of the few things they have to go on to figure out how knowlegeable and hard working you are.

If you have been out of school for many years, and working in the field in the meantime, grades very likely wouldn't matter or at least wouldn't matter nearly as much.
