I applied through college or university. The process took 1 day. I interviewed at Kariwala Industries (Calcutta) in Jan 2020
Interview
Easy interview process was really easy. First they will take a written exam and then if you pass the exam they will take you to the next level which is face to face interview. They questions they ask are mostly easy. But the difficult part is when you are meet the director. There you need to be really honest and updated about current affairs.
