The skills and passion of the team members are key points. The size of the team may play in the favor of applicants, but is not a requirement. A single candidate who can show a portfolio of successful projects will have the same chances as larger teams.
Commitment from the University is a strong requirement. Students need to demonstrate that their professors support them, and will give them time to work on the projects. The ideal situation is for a team to pick a MWoS project as their final thesis, and work on the project for a full semester. Not all students will be able to do so, and we will evaluate all applications with the same level of scrutiny.
=== Are multiple universities allowed to collaborate and have a single team? ===
Yes.
=== Can I still work on Mozilla projects if I am not selected for MWoS? ===
