Pros

There are many smart and talented people working here, but unfortunately, they are completely unappreciated by management

Cons

The environment is deeply toxic, driven by gossip and fake smiles from people who will gladly stab you in the back. Compensation is tragic for engineering roles—expecting you to work non-stop while capping pay at around €1,200 in the best-case scenario. Management is incredibly reactive; they only adjusted salaries once after a mass resignation of 4 people at the same time. Financial growth and promotions don't happen based on merit or hard work; you only move up if you play toxic corporate politics and diplomatic games. Avoid this place if you want to be judged by your actual skills.
