I'll definitely agree with you in some ways. Two or three years into a career, no one is looking at your GitHub. But when you're just in college, a quick look through your GitHub can be a decent filtering function that I frequently use when I visited colleges on recruiting trips. A follow up conversation about some of your favorite projects and what's something interesting you've learned or done recently helps me catch those who don't have a GitHub or have lots of projects that aren't really theirs.
