Pros
I didn't get enough time to see any Pros.
Cons
Alten doesn't have a plan for the consultants that hiring them, once you receive an offer you will join then they will start searching for a customer for you, and If they don't find a customer they will terminate your contract before completing 6 months depending on your probation period then will try to hire another one with the same profile skill and repeat all the steps again. they don't care about you or about finding another job even if you didn't get any chance to meet any customers, and the reason for them will be the market is down now we are sorry, although they were having the same profile skills they will try to hire another person to get the benefit of the probation period and you can't do anything, they are following the same approach over and over they don't care.
