Suggestions on what to do if I get an Internship at a very young company.

So recently I have recieved an internship offer through referral. But the company was established in 2025 and I am also entering my 4th year. So I have to prepare rigorously for placements as well. The company's founder and co-founder has really good experience. . This will also be my first corporate experience. So I am very confused on whether to join the company or not.
