Involves a written test which is very basic . Anyone with basic mechanical Engineering can crack this . Cracking this exam is a cake walk , Dont stress about studying anything technical . Just go with an open mind . You'll easily crack it . The trickier part is the interview . Be ready to be grilled with technical aspects from your internships and projects . But what they really looking for is an avid learner . Just have a healthy conversation with the board . I fumbled in a lot of place. Just be positive and answer to whatever level you can .
