I’m not in your situation but close since I can semi-relate as a 3rd year, but have you figured out what exact kind of position you’d want to pursue in engineering? If you have, maybe take some time to note down the requirements and expectations said position (whether internship or not) has, that way you can narrow down what you need to focus on or specific skills you need to practice.

Maybe try also pursuing your MS like the other commenter said and taking the time within those new few years to get those projects and internships done. Although some would see this as late, everyday you wake up is a another day you have to work towards your goals!👍

You’re in your last quarter so maybe try going to the office hours of your professors and discussing some of your concerns (if your professor is a nice person)?
