Arranqué con una entrevista personal bastante centrada en conocerme y evaluar mis fortalezas para confirmar el encaje con el rol. A partir de ahí incluía una breve prueba técnica para validar competencias esenciales del puesto. Me dio la impresión de un proceso que quería aterrizar rápido si lo que decían que necesitaban coincidía con lo que yo aportaba.

En otra parte del mismo tipo de recorrido, el proceso me pareció directo: hice un total de tres entrevistas antes de llegar a una oferta. Primero hubo una llamada telefónica para contrastar datos de mi perfil y background, luego una entrevista con el manager del área y una final con HR. Lo bueno de este formato es que el orden era claro y el avance no se sentía caótico.
