When I was in college, I took a class that was dedicated to working with a startup on a piece of software. I wasn’t paid and wasn’t necessarily “hired” but I did work with a team of students + stakeholders and made an impact on the company.
My question is: should I put this on my resume/linkedin as work experience or a project?
Yes! This is a plus point. I have conducted a lot interviews, and it sucks when students don’t have experiences with personal/team projects, just the basics from their University or what not. This is a good thing!
