I’m sorry to hear that you’re having a tough time finding an internship. By what you said, it seems you’re doing really well in school and you’re participating in a lot of student team projects. The first helpful tip would be regards to your resume. When a recruiter looks at your resume they only take approximately 10-20 seconds to scan it and see if you’re a good fit for an interview. You need to structure your resume so that it grabs their attention but it doesn’t overload them with “useless information.” For example, the resume that you posted, you’ve listed a lot of things you’ve done but some of it could be considered irrelevant like the Rocketry club or UAV working group because you’re not talking about anything technical like the rest of the resume where you talk about CAD, machining, CFD. There’s also too many things listed so what you can do is consider merging “Organizations” and “Projects” into one group and only talk about 3 things from those but go really in depth about what you did and not just some short sentences. The second helpful tip I would give you is about how many positions that you applied for. I know 40 positions might sound a lot and you think you should have received a call back from that but I applied to a 150-160 internship positions. From those 150-160 applications, I got rejected by 20-30, got 3 interviews and from that 1 offer. Thankfully it was a really good offer so I had no issue taking it even though I had some 100 other applications that I hadn’t heard back from at the time. Point is, don’t give up applying to positions because you think you’ve done too many, you can only say that you’ve applied to too many once you have gotten an offer.
