I went to SCA and majored in Cinema and Media Studies. I have had several unpaid internships. I have in the last year, I haven’t been able to get a paying job in the film industry. 
Well good luck securing one soon. Have you created a linkedin profile and tried marketing that way too… especially with USC and USC SCA alum? There is even an USC School of Cinematic Arts group there. Networking is key… especially during your first couple years after graduating. I would do your best to reach out to fellow SCA Mafia members.
Sorry to hear that OP, keep trying and don’t give up! Send multiple resumes daily, follow up, and keep a positive attitude.
Have the others from your CAMS cohort found jobs?
Were you able to build a network while you were at SCA that you can reach out to?
Did you work on student sets while at SCA? Did they ask you to come back? If so, reach out to them now since they have some experience with you.
