Our goal at Minorio is to help engineers get jobs, we believe that experience in a well known open source project radically increases a candidate’s CV value and their odds of being invited to an interview.

The best open source project is one (1) you are excited to work on, is (2) welcoming of contributions, and is (3) well branded (typically because there’s a company willing to put in marketing dollars behind it)

To figure out if contributions are welcome, look at the project’s pull requests, are they active, do they include more than a few core developers, how stale are PRs - a lot of broad activity here is a great sign.

You might want to get at least one PR accepted before offering the project to new interns.
