BNP Paribas interview questions

Got a call from consultancy and they have forwarded my Profile to BNP Paribas. My profile has got shortlisted and they asked me to come down for F2F. There was immediate requirement with only 1 vacancy. I just went and had technical interview that almost 90 minutes with SQL & UNIX. Panel asked me to join in 10 days but I said I can join max in 30 days. Next day I got a call from HR stating that I have clear the technical round but due to Notice period your profile has kept on Hold. They hired one guy who is ready to join immediately. After a month I got a call from Same HR, Stating that they got 1 more vacancy for the same project are you available for interview, Immediately I said " Yes" again she scheduled my tech interview with same panel with Managerial and HR round, Finally had a HR discussion regarding salary discussion and they gave really good hike. Panel, HR was very friendly.. Finally going to join BNP paribas in Aug 2015
