Hi buddies,

I am from Chemical Engineering. I have attended JSW last year in my college Campus.
3 Rounds are there. Written, GD, PI.

In Written exam full technical questions are there. I have provided the question I can recall now. About GD, topic is from general education based, or current affairs.

Two PI round, Tech and HR. Questions was asked from vocational training and hobbies. Self Introduction is very important. Hope these will be helping you a lot. Best of Luck.
