Release from Societe Generale client as a Data Engineer

Hi All,

I am a Capgemini Employee working for Societe Generale client from the client location. I have completed 8 months with CG and 7 months with SocGen. I want to put papers now. Will the SocGen ask me to work for a 3 month notice period or would they give me an early release.?

If anyone has the slightest information regarding this situation, please share.
