Guy's please help me decide whether I should quit this organization or not

Basically, I joined this startup 50 days ago as a Digital Marketing intern. The agency is based in Noida, while I live in Gurgaon. It takes me 2 hours to commute to Noida daily and the same amount of time to return, making it a total of 4 hours of travel every day. We have a 5-day working schedule, and I dedicate myself fully to my work with passion.

However, the founder assigns work on Saturdays and Sundays as well, not the whole day, but tasks that take 2-3 hours to complete. Because of this, I have no personal life. To make matters worse, my internship stipend is just 10k , but the startup seems to want to extract every drop of my energy. Due to the additional work on weekends, I can't even take time off to enjoy or relax, which leaves me completely exhausted.

At the very least, we deserve our weekends free. Should I quit this organization after my internship and avoid joining as a full-time employee? Also, it’s not just me—this applies to full-time employees too, who silently put up with this.
