During the third seminar, organised by CEDIT on the 26th and 27th November, each partner of the Erasmus+ RMT project presented the survey conducted on their network of companies, on the perception of the competences acquired through international mobility in terms of professionalization. In total, 170 European companies were interviewed. We then validated together the data analysis methods to establish guidelines and thus ensure the harmonization of all contributions that will be integrated into the second compendium of the project.
