I vastly prefer to see portfolio work, and when I assist in screening resumes, I always look at the people with portfolios first: they provide the most signal. How does your code look? How do you interact with others? When I'm doing deeper interviews, I check the portfolio as well: what is the specialty and interest of the person? What are they up to? Do I want to work with this person? At the end of the day, we're both human beings, and we have to get along at work. I don't want to be in a bad relationship. So I look at, and prefer resumes that give me the most information to this end. Other people do it differently.
