Caveat Emptor
If you are considering contracting via Capgemini, I recommend that you think really carefully and do a lot of due diligence. They treat contractors very poorly indeed, their administrative systems and services are burdensome and poor and they work hard to avoid paying. Experis are a complete nightmare as they have no understanding of IR35 regulations and their contracts are just a pile of poo. They often body shop to other companies and therefore you are worth nothing to them…and boy do they let you know it
