Hiiii frnds Im Sandeep Bhatia,i have given ONGC written test on 25 oct 2009 in Delhi,im frm mechanical branch. The pattern of exam was 40 general awareness questions and 80 technical questions plus 4 subjective questions(2 general awareness and 2 technical) and there was no negative marking. First ill talk about general awareness.It consists of both current affairs knowledge and basic general knowledge which means that if u study newspaper daily & thoroughly u can easily attempt 20 questions and if ur basic general knowledge is good u can attempt rest 20 also(for this u can refer any general knowledge like S Chand RS aggarwal).questions are of al type politics,sports,authors,economy etc..it also consists of two subjective questions which are for this time: 1)General awareness against global terrorism. 2)India's economic condition in recent recession time. Second is technical part which according to me was very easy as compared to written test of all other companies like NTPC,DRDO,JSW etc..just u need to go through the basics of all subjects,no need to in detail of any subjects,there were 5 6 numerical which were very simple and formula based.they were covering almost all subjects like KOM,SOM,FM,MV,Thermo,INDUSTRIAL,OR,PT,MS etc..It also consists of two subjective questions ,out of which one was from IC ENGINES-thermal eff was given,mech eff was given,CV of fuel was given and BP was given..u have to calculate fuel consumption in Kg/hr and specific fuel consumption.Another question was theoretical question-explain cutting tool materials and cutting fluids. Wish for me and good luck for ur future. Remember that NOTHING COMES WITHOUT HARD-WORK SO JUST WORK HARD AND LEAVE REST ON GOD. & also THE REAL TASTE OF SUCCESS IS AFTER STRUGGLE.
