Stuck in nothingburger job post graduation

Hi everybody. I'm a may 2025 grad and data engineer at a pharmaceutical currently. It's a mid sized pharmaceutical and I do real data engineer work and design LLMs but the name has 0 pull. I make mid pay but I'm grateful to be employed regardless. I've been applying to jobs at bigger companies but the lack of entry level roles is killing me. I unfortunately only see now that what you do in college and where you intern is the only thing that can get CS majors far anymore. Honestly that's probably always how it was, but if you do nothing you're fucked now. I somehow got lucky with my role as I had interned there before. I've been grinding DSA and making projects each month and keeping my Github, LinkedIn, Portfolio, and whatever updated. I apply to maybe 150 jobs each month while working and have gotten call backs from 2 or 3 in that time (admittedly blew an interview recently). I am honestly considering going back to get my masters so I can apply to internships and get some redemption for my time in college. I don't want to be stuck but it's so hopeless. I apologize if I sound like I'm ungrateful to be employed but fuck dude
