For college juniors/seniors with more CS knowledge, but without the time for a full-time internship.
This is the right track for you if you're a college student with experience beyond the 101/102-level CS classes, or a student who has built projects on your own time (e.g. hackathons).
You'll be matched with a mentor from the technology industry, like at most traditional internships, and will build a polished app/feature.
(No fee. Not a paid internship.)
