If you are going for interview make sure you are so early coz finding datamato isn't easy. Their is not even a single hoarding of company on building. So coming back to interview, first round was GD held at Profound Edutech, 2- first technical round at Profound (basically check confidence and communication and basic java) 3-Second technical round at Datamato(questions listed below) 4-Hr round (I don't about it because I got rejected) Overall interview was very easy. Just check basics of DevOps before you go.
