No interview process as such. They just asked me casual things about my experience, my previous company, my way of working.then was a final discussion about coding .then was a final discussion was delay

It was like college practical viva. they only asked the basic questions but the process took the whole day since I have to wait for hours after each round. There are 4 rounds. two were basic technical and after those one with HOD which did not have sense how to speak professionally he asked every question with attitude. However i cleared that round and hr asked me too many things which was having no sense to job. they gave me very less hike so i did not go to further rounds
