Trying to Change Careers

I'm a non-tech nonprofit worker trying to get into a social media company. I've had high-profile work with well-known partners throughout the years, measurable results, etc. but I can't get a single call back and I'm wondering if it's the names on my resume. Ironically, I had rounds of interviews with Facebook a few years ago, but now it's dead silence. Any advice for switching from nonprofit to for-profit or even just for networking into some conversations? #Reddit #Facebook #Google #Twitch #Discord #Youtube #TikTok #hiring #mentorship
