In this work, we describe the analysis methods used in the creation of two original visualization interfaces in the field of e-recruitment. These interfaces were designed using millions of user profiles gathered on social networks as well as thousands of job offers collected over the internet. This work also describes the necessary steps for the implementation of the interfaces. The first visualization is a dynamic map indicating which jobs are in-demand, in which field and in which region. The second visualization tool highlights career paths and allows the user to observe the perspectives as well as the antecedents for each job considered.
