Here is another great tip to make the most of your internship:

Cooperate And Participate

If ever there are meetings or seminars that you're invited to, try your best to attend. These could be very useful in understanding the way your company works and operates. You can also learn how people in the company communicate. You can understand more the connections of different departments, especially if you're working for a big company.

Attending such events can also inform you on the different opportunities related to your field that you may be interested in, in the near future. You would also improve your interpersonal skills along with your professional skills, if you don't let opportunities like these pass.
