The thesis that gave rise to this book sought to identify the specificities of the research participants' trajectories and advance the understanding of the process of professional insertion of young adults with at least a master's degree, in its multideterminations. The analysis, enhanced by the methodological choice of biographical interviews, sought to understand the phenomenon under investigation not in terms of cause and consequence, but rather to understand the specificities of the factors that characterise the different paths taken by these young people.
