Accenture Network Engineer interview questions

Not sure why some companies bother to conduct interviews? To keep their PM s busy or to waste our time? I wasn't asked any technical questions, it was like a general chat about work place and my status there. He even told me that he can get me on board but I shouldn't resign until I hear back from them. What an unprofessional attitude! Never heard anything , then I called the recruiter who set up the interview and he was very nice responded quickly, and quoted the feedback! " He is more like a support person than a leader ". It didn't say in the JD that they are looking for the president of the company! Not sure how he decided that in 15 min conversation!
