TBH I'm not even sure how undergrads get research. I have actual research experience in a military lab and every prof I've asked about research opportunities has said, "we don't take undergrads in our labs and on the rare occasions that we make exceptions, it is only for those who intend on pursuing entry into a Ph.D or master programs." I've only met three undergrads at my school who got research and two were seniors who essentially lied and said they were interested in Ph.D programs, lol. My TA told me they hate undergrads in the labs because the training we do in undergrad laboratories in no way shape or form prepares us to actually work in a research lab, which is something I've been saying all along 🙄
I do know of some people that do research outside of the university, but in-house research for undergrads seems pretty much non-existent at my school.
