They will ask questions from topics in which you are not well versed, and once the 1st round interviewer knows your weak subjects, the 2nd round interviewer will ask questions specifically from that topic, to lower your self esteem, and manipulate you that you are not good enough. So that they can offer you less package and convince you that you dont deserve more than this at this point of time. I witnessed too much office politics just during the interview process. They also make you sign 2-year bond. In short, this is a scam company, less salary, 2-year bond, no other perks.
