Certainly some people come for the money and stay for the experience. My best advice for internship applications is try to have some interesting project on your resume --- preferably one of the things you've been working on outside of class, but mention interesting class projects if you can speak to the whole thing. And get the interview basics down -- clean clothes, appropriate clothes (ask recruiter/scheduler what people wear to work and match the fancier end), arrive 10-15 minutes early, try to be relaxed, etc. For video or phone interviews, if you can find a quiet place with no distractions, that's best. It helps to do practice interviews, which could be for local companies you might rather not interview.
You didn't ask for interview advice, but I just mention it because I've interviewed some intern candidates, and it's always unfortunate when the candidate seems very unprepared or having a bad day, but may have been a good fit.
