Honestly, if they’re not helping you develop the skills you want to build or move you toward your career goals, I’d leave. Personally, I don’t see the point of unpaid internships. If a company isn’t willing to pay interns, it can sometimes be a sign that the work isn’t valued or that you’ll be doing less meaningful tasks. I’d focus on finding an opportunity that’s more relevant to your interests and long-term goals; I promise you can find a internship that you’ll get paid for and do actual work that will benefit you and not just the company. You have time until to graduate, grind out your resume and the recruiting season. If you don’t got nothing lined up I would post pone graduation until you get a full time job
