Hello sir,
I am final year mech.engineering student.I need NTPC's last 5 year Executive trainee question papers.
plz send me.

plese give me aprevious year n.t.p.c paper, and also tell the latest paper formate of n.t.p.c recruitment m.t for mechanical engiuneering

NTPC,

India’s largest power company, was set up in 1975 to accelerate power development in India. It has emerged as an ‘Integrated Power Major’, with a significant presence in the entire value chain of power generation business.
NTPC ranked 317th in the ‘2009, Forbes Global 2000’ ranking of the World’s biggest companies. With a current generating capacity of 30,644 MW, NTPC has embarked on plans to become a 75,000 MW company by 2017.
