They told me that this is one day interview process and they will conduct final round same day but after selected me in final round they called again some other day and took one more round which was related to quants questions instead of examination of communications and presentation skills

2 rounds of Zhund interview, anybody can crack, if you couldn't then you should better start working on your skills. Strongly recommend not to waste your time here, it will just help you to degrade your value in society...
