If you're looking for an experience that you can confidently talk about during an interview, consider participating in one of the Learning in the Community (LINC) courses. These classes are project-based, so they may take some time to do (~ 10 hrs/week). This is especially true for those who have not yet had internships and/or research experiences.

ENG 298, 12:30–1:50 PM, TR, 3 credit hours
open to all students, all majors, all levels
