Wind World Software Developer interview questions

I was interviewed at Wind world Mumbai for position of software developer . I got a call from wind world HR , she told me ill be facing 3 rounds, 1st: Technical F2F round, then Head of department round and final HR round salary and all .. They took my f2f tech round and it was good for me. Person who took my interview was nice , he read my full CV that was good, else i see some employee's dont look at cv and start firing stupid question which are not relevant to our experience. Anyway they wanted me to join in 20 days. But my notice period in current company is 2 months. So they dint consider me .
