These companies are probably right that their size will protect them. People who are currently employed know better than to take the abuse. That's why these major companies recruit so heavily at colleges and rope in people who have zero perspective on work who don't know any better.
I had a poor college GPA. I missed a lot of good job opportunities because of this. However, it made me un-hireable at a lot of large companies that I might have considered at the time.
