The interview questions were pretty normal regarding the role, But I don't know why the interviewer never responded to any questions I asked him. I asked what was his name, he never responded, I though probably he didn't heard me, so I asked him again, he didn't said anything in response, it became a little awkward. I don't worry much about awkwardness during a conversation, but again I asked him about how he will approach a problem that he asked me and I answered in one way, he again didn't answer at all.
