Capgemini fake hiring

Why is Capgemini doing fake hiring. I mean they are taking interviews multiple times. Is they really show casing the hiring of clients? I have attended 10 times for Capgemini interview for plsql developer position in last 1 month. Everytime some 3ed party recruiter call me and take details ofnmy alternative email and arrange a call from Capgemini. And loop continue. Why these PPL waste our time.
