BT Group Technical Delivery Manager interview questions

A recruitment agency called me up and scheduled a round with the hiring manager face to face at BT office in Bengaluru. The job description was an essay in itself. When I stepped into the room, the hiring manager wanted a print out of the JD, that gave me a signal that he doesn't know what role is he hiring for. It was more of an interrogation session than a discussion, and interviewer had 0 people skills. I shouldn't have wasted my valuable time in going to their offices in person.
