Questions posées lors d’un entretien d’embauche pour Core Java Developer chez HCL

1st round for some project in chennai they conducted. It was not even communicated at first that relocation was needed for the same. At the end he mentioned whether ready for relocatio and I mentioned no. So this process was scrapped fully and my resume was handed over to some bangalore based project. If relication wad mandatory then why the drama of 1st round of interview before taking consent.
