Looking at your portfolio -- are you applying for video game jobs or generic Big Co software engineer? Or pretty much anywhere you can find / that reaches out to you? Try for something outside of your experience, or even something you might think is "beneath you", selling yourself as a new college grad eager to grow your experience and be part of a team. Also consider applying for SDET jobs after learning some basics about in-vogue testing philosophies. Other than that, I second the advice that it's just a numbers game, keep trying as long as you're able, and if you can up your job search into a full-time activity (i.e. 8 hours a day spent on job search) that's even better. Once you get your foot in the door, even as an engineer-in-test, you can start transitioning within the company more easily as well as continue looking elsewhere without the stress of "I need a job now to pay bills."
