I am a second-year Math and CS undergraduate in the US. I am beginning to consider my prospects for graduate school, or possibly industry research.
My research experience thus far is from an internship at a private company. I do not participate in client work, only in proprietary/confidential R&D. In terms of demonstrating results, my work is at best reported in an internal whitepaper or two. Otherwise it's strictly confidential. The only thing I have to show for my work is a cleaned/approved resume blurb.
Thinking about my application from the perspective of a University, I feel like my research experience really just looks like I'm hand-waving results without anything to point to. I really enjoy the work, but I am worried that its lack of visibility will hurt me in the long run when applications roll around and I have nothing tangible to show for it.
Is this a typical concern? Or is this enough of a reason to request to participate in research presented at conferences or switch to research at my University instead?
