As someone who's hired a few interns, I like the idea - having a place I could quickly brief myself on a potential interns projects would be a real win for me, and not something I see on most college resumes - so kudos to the recruiter at your school for some useful advice!
I'll contradict the recruiter slightly with the thought that I certainly don't want to see any minor homework projects that are so small you can't really talk about them. My metric would be:
- absolutely highlight any year long or half year long work (ie, a project that transcended the semester) - typically these are either self-motivated, or part of a graduation requirement
- hit 1-2 projects if they are whole semester/term projects
- skip anything half a term or less in scope
If you have 1-3 bullets in this section, you're doing great. The idea here is to give the person you'll be speaking to enough meat to ask a decent question. If there's not enough to the project to warrant talking about it, then skip it. The things I like to see most are projects that involved:
- work so big you weren't quite sure how to break it down at first
- examples of team work where you can talk a bit about group dynamics
- work so big that you had some major hurdles part way through and had to overcome some interesting obstacles
- if you managed to prove/disprove something surprising or brand new - even better
That's the kind of thing I'll probably ask about as we do an interview, so having a quick reference to the project, it's length, it's goal, and maybe 1-2 key techologies or topics involved in it, is the most useful, since I can quickly learn the topics if they are new to me.
What if I don't have any?
Then skip it. Highlight coursework, prior experience and job history.
At least when I went to school, many sophomores hadn't gotten there yet. But many Juniors had. In looking for a tech degree, I'd advise any college student to try to take advantage of the opportunity to do such a project before Junior year, as it shows a depth that will absolutely help with internships. But often many programs can't really accommodate this sort of complex work until after basic coursework has been accomplished, and that may be after sophomore year is over...
