They ask unnecessary questions and they even ask project related questions that shouldn't share with anyone ,how they ask such a questions , they're also part of some organisation they should atleast understand this much Their interview for a single person long duration even though they know the person capabilities after asking few questions

It was nice. Straight to intro and questions. It took about 30mins to complete the interview; he asked about project and skills and questions were majorly on DB2 like writing queries and all.
