Very poor management, HR is inexistent, miserable salaries and the company is full of arrogant and lazy bosses”Managers”: opiniones de empleados con el puesto de Empleado anónimo en ELCA Informatique

Absolutely a disaster, the stress level is enormous, there are not enough engineers and technical people, unlike managers, there are a lot of managers who are useless (they have invented new positions just to hire a new manager) most of the time they don't have no idea what to do, so they tend to stress the engineers to justify their salaries. There is no career growth, besides all the suggestions you propose come to nothing, they don't want to change because they will have to fire most of the managers. HR is inexistent and arrogants. Basically, never think about working there if you want a good career and a happy place to work.
