The person taking interview was snot sure of what was the JD like there was a gap in what was communicated by the consultant and HR and what the person interviewing asked. If you are hiring for Java, please explicitly mention the same in JD.

Got a call from recuriter and it was a Telephonic interview. Interviewer was looking for some specific words in the answer and if not there just moved ahead. He was in hurry to wrap the interview seems like in first 5-10 minutes he made up his mind about the result.
