I applied through my campus program . There was one question that was to be solved in 3 hrs in the online assessment . 50 test cases had to be passed to be selected for the interview . I solved the question nearly in 40 mins . In the interview , i was given an optimization problem where there was a building that had 12 floors . I had 3 lifts and i needed to optimize the scenario where i had to tell how would i place the three lifts and what plan of action would I floow.
