Roquette Executive Engineer interview questions

First round 50 marks written exam, which included 15 marks general knowledge. All the questions were of basic level. Second round was technical interview. In the 2nd round, other candidates were interviewed for about 10 to 15 mins. But I was interviewed for about one and half hour. Finally he told me that I'm selected and I will be called within few days to meet the unit head, who will decide the final selection.
