I have seen this happen when a friend of mine switched from studying medicine to software engineering. Don't give up on internship, they really matter. You have an age handicap (you'll be lying to yourself if you don't admit it), however you can overcome it by being better then what your classmates are offering. You bring something very unique to the table, experience and knowledge, try leveraging what your learned as a mechanical engineer into the interview, show them that you have a unique and broad perspective (especially if you're going to intern in an IT department in a company that is relevant to that process)
