It was a hectic process, there were a written exam and 3 interviews, where i passed all of them but in the final call i got declined because my major in undergrad was Apparel Manufacturing and they aren't gonna hire from that background even though they knew my educational details from the get go.
The interviews and written exam were fine and nothing too hard.
good technical knowledge about textile industry should be enough, and ability to be good in English also analytical math problems is required for written exam.
