How can I get more internships?

Here are some action items I recommend:

• Clarify success criteria - Figure out what the outcome of your current internship is. Is it possible to get a return offer? If so, definitely optimize for that.
• Leverage school social programming - One of the greatest perks (usually) of 4-year universities is that they'll offer job-search programming, mainly career fairs. Make sure to tap into those aggressively. Polish your resume, show up early, and come prepared!
• Network at your university in general - University is an awesome environment as there's a lot of solidarity (your fellow students are around the same age as you and at the same stage in career). Here's also a great discussion around networking with folks more senior than you: "How can I network effectively as a college student?"

For more in-depth advice on how to navigate the job market as a student, I wrote an article about it here (it largely covers the mistakes I made as a UCLA CS major, haha): How To Find A Job As A Computer Science Student

Having a terrible resume is also another super common trap I see students fall into, myself included. I made a course to fix that, stemming from my experience writing a complete garbage resume as a college student and then going on to review 1,000 resumes across every tech company I've worked for: Get More Interviews: Write A Stellar Resume As A Software Engineer

Lastly, I highly recommend this other discussion: "How to make the most of my time in school?"
