The interviewer was very polite and asked me questions related to basic java, basic java code asked me to write, asked about sql and a query to write and in last he asked me a puzzle.

Extremely unprofessional. Its a 10min interview in which they'll ask fast track questions. If you seem to answer correctly they'll interrupt you and ask another, but if you mess up, they'll drill you down. They don't even care what we are skilled in. He started asking questions in Java until I said him -please change it to python. Its just another Mass Recruiter with 5lpa CTC.
