My friend worked at Google a few years ago (in a non-engineering role). After his in-person interviews, the recruiter called him back to ask him how many hours he worked during college (to pay his way), so as to excuse is less than 4.0 GPA to the hiring review board. He had completed his undergrad degree was 20 years in a subject not directly related to the Google position. He since had an relevant MS degree and real-world work experience, but that undergrad GPA was apparently still really important.
