Capgemini Invent Test Automation Engineer interview questions

It was walkin..I reached 2 o'clock. Recruiter was there he asked me for skill and domain and he was suggesting not to give interview. But I submitted resume for interview. Within 15 min I got chance to have interview. Interview was too good they asked to write code for selenium web driver and after that java concepts. I got selected and recruiter was not happy I don't know why..on Monday I got mail for documentation.On Tuesday I got salary negotiation call at 8 pm. I told him this is my package and I am ok with what you will give it to me. Next day system generated email triggered to me saying that you have not selected. I talked with HR he said ignore that mail it was by mistek to you. I had hope. Next Saturday I again meet that recruiter he asked me my name and said you are not selected and again next Monday I got mail from them for availability I replied to them yes I am available after some time again I got email that you are not selected.....Don't go for interview in capgemin most of time HR do backdoor only
