This is where having a good GPA matters and going to a good school. If you want to go to school to learn, that's cool, but don't think it's going to get you a good job.

If you were in the same Greek house as the hiring manager, your chances go up. If you went to the same school or went to a prestigious school like Yale, your chances go up. No one is looking at your GPA at this point though.

You really have to go out and socialize. It's not enough to just have a degree anymore. You need to do projects. Contribute to open source projects. Go to meetups.

If you have Google on your resume, you're good. It doesn't matter how good you did there. Employers look at this. If you start your career off on the wrong foot, it will follow you around for the rest of your career and it may be difficult to get out of it.
