Engaging in the community, whether it's asking questions, helping other students, contributing code, filing bugs, or whatever else, is a good sign that you're actually interested in our work and our projects.
 * **Communication skills and initiative**: These are essential to completing a successful project. Things we look for (among others): asking specific and detailed questions, following up on conversations, making sure to read available resources before asking questions, being patient and responding to critical feedback well.
