Pros
Alten is only good as a starting point in the career. Nothing more can be added
Cons
The Alten doesn't really care about their employees. For them is the client the most important. The trick is they give a 42 hours/ week contract in the company where the official working hours are 40h/week so even if you have an overtime, you will never get paid but themselves will charge these hours to the client! No communication from the management, hardly reachable manager and the top is the mood radar they sent as they are not aware that employees are unsatisfied. And even if you write what bothers you, no one will react! If you want to develop in the career, they will not support you with an excuse if you are less then one year on the company but also if you are longer, they will say "We will discuss it internally and let you know". Never got a feedback and also not the training. They are only good in promising but not in actually fulfilling the promise. I wouldn't recommend this company to anyone!
