After this again people will be shortlisted if u r shortlisted for the next round u will technical interview (the questions will be based on whether u r shortlisted for hardware or software) if u r shortlisted in both category u will be given choice to select any one .finally in our college puzzle round was conducted but not sure whether its the same everywhere.
