Example of a strong PDF portfolio for job applications?

I’m applying for summer internships, so honestly I’m trying to cast a pretty wide net just to try out different industries and see what sticks! I’m really interested in athletic/outdoor gear and apparel; planning to focus somewhat on that, but I don’t want to get my heart totally set anywhere specific at this point. Trying to split those applications between some of the bigger multi-sport companies and a bunch of smaller, more niche places. I’m hoping to get away with one PDF that’s focused on outdoor and softgoods work, and 1-2 separate PDFs for other industries?
