- The number of potential job candidates, and therefore costs associated to their hiring, has grown significantly in the recent years. This is mainly due to both the complicated situation of the labor market and the increased geographical flexibility of employees. Some initiatives for making the e-Recruitment processes more efficient have notably improved the situation by developing automatic solutions.
