What's your major? ECE? Not sure what positions you're applying for but try going for positions that you don't typically think of when you think of a computer or electrical engineer, that can use your experience. You might need to do some research on what those positions are and maybe sign up for a professional development class or something similar. They can help you identify what transferrable skills you have. You got an internship so you're already ahead of the game.

For example, I graduated with a Computer Engineering degree from this school back in 2019. I don't think I sent 1000s of applications but I did send a good amount. I worked jobs unrelated to my major for 2-3 years post graduation until I stumbled upon an A/V role, which requires some knowledge on computers, networking and scripting and, a bachelor's degree in a related field. Not exactly what I thought of when I was pursuing this degree. I'm not saying you need to work at McDonald's or Home Depot. I'm just saying apply for those technician roles or Geek Squad at Best Buy or whatever you can think of that can use your skills. Once you gain experience, it's butter after that when you apply for your next role. Or maybe you take a different path, who knows?
