Pros
HR team is helpful, they are really nice; Provides non-paid trainings, if a training need payment, forget it or become a people likes complain; Alten manager does not follow your mission so much, except you have another offer; Provides check de vacance, C.E.
Cons
If you are a foreigner not French, you probably will be depressed after 6-12 months; Very very very low salary; if you want to ask salary increase, it is more difficult than get a physical+psychological double degree P.H.D diploma; If you are talent, it is not a good choice, if you are not confident with your skills, it is a temporary place; They know you will not leave within 2 years, and after about 1 year of working, after you notice your salary is so low, you still need a log time to find another offer, during these 2 years Alten will not increase your salary; Remember, you are just a number for Alten, not a friend, don't be stupid too much.
