We @imagineenpc.bsky.social are slowly but surely entering our proposals for master's degree internships here: https://docs.google.com/document/d/1g6WZptYAPf5CcTz5BQ3-bWSoW_Dz3SnJL5erxuikLNM/edit?usp=sharing
These are 6 months projects that typically correspond to the end-of-study project in the French curriculum.
Probably more offers to come, check it regularly.
