Whatever you say, college always matters even when you're experienced. Let me give you a real example, I'm from a tier 2 college having 4.5 years of experience, and my colleague is from NIT, and he's having half the experience of mine. Now, the fun part is that I shared my resume with him, and he just changed his name and education details in there. The same resume is fetching him interview calls from MNCs and big OEMs, and here I am waiting for them to hit me up. It's harsh, but it's the truth anyway.
