The interests area is located at the bottom of your LinkedIn profile and shows six main interests for someone to see, with a link option for readers to view more.
LinkedIn will add these specific things to your interests area:

Any company or organizational pages that you “follow” on LinkedIn
Any groups that you actively participate in on LinkedIn
