Public service examinations

Public service examinations (concursos públicos) are part of my trajectory, both as a candidate and as a civil servant. I passed eight competitive selections for economist, professor, judicial analyst and municipal attorney positions, three of them in first place, and I was also certified in the National Judiciary Examination (ENAM). I still sit public examinations and follow calls, examination boards and the structuring of public careers, which keeps alive my interest in evaluation, management and personnel policy in the public sector.
