Keep in mind that internships can be an excellent gateway to full-time employment (not only with FANG companies but with many other firms and agencies.) You can seek out colleges that seem to have good internship programs (https://www.usnews.com/best-colleges/rankings/internship-programs) or locations where IT opportunities are especially rich. The latter includes Silicon Valley, of course, but also the NC research triangle, Boston/Route 128, Baltimore-Washington-NoVA, and many other urban centers (although school location isn’t necessarily a huge factor if you arrange to do internships between terms.)
