Pros
Plenty companies in the area offer what alten offers, but depending on the client you don't need to speak french fluently.
Cons
Pay will, at maximum, get to 42k per year, if lucky and well considered. Pay starts at 32.7k, which is severely underpaid in a rich and expensive area. Managers don't care about their workers and are only interested in their bonus, which they get by hiring new people. They rotate even faster than the employees. Their salaries starts at 40k, their bonus is of 20k, for their first year. I am not aware of their max. Managers mention trainings which never seem to come your way, yet they assure you that they will accompany you in your growth. They have internal campaigns to raise the glassdoor rating. Some managers are xenophobic. When a bad manager is fired, the rest say they did not represent the Alten values, yet it seems to keep happening. Seems like simultaneously a bad manager is hired when one is fired. They assure you that you will have French trainings if you are not French, but if you don't push for them they will not happen, and if you do, you will have group lessons after 5 months, and hopefully 10 hours of call 1-1 lessons after another 5. These will not help you learn French meaningfully. They overcomplicate expense reports, and even suggest that you are filing too much in expense reports when you go over 80 Euros/month, and you should change them.
