Pros
Restaurant tickets Not really a lot. They promise you more advantages they actually offer.
Cons
They hire you without having any mission for you. Then you spend weeks talking to different business managers, trying to find a mission for yourself (what your manager is doing is unknown). They say they help you to find a home in Toulouse, and that they will pay for this service (they subcontract it to another company to avoid called Seed & Moove). Actually, Seed & Moove will do formalities in your name for APL and they will receive the money the French government sends you to help you pay your rent (they were surprised I discovered this). And if Alten has problems, they do fire people in the trial period (they give an impossible mission in a very short period of time and then they say you did not achieve "their standards" of quality).
