Got an interview but...

Hi everyone, I made an account to ask this question as I don't like social media. I'm a senior in college; spring is my last semester. I applied to the job due to a recruiter messaging me on LinkedIn, and after a little research (making sure the company is real & not a scam), I decided to apply -- I have nothing to lose by applying.

Obviously, I won't get the job. I won't be able to relocate until I graduate. But my question to everyone is, what can I say to the hiring manager to express my interest in a job after graduation? The job market is in shambles, and I feel like I am missing a big opportunity by not taking it (if offered).
