The paper consists of 60 technical and 50 GK questions.. out of 60 we have to do 50 and in the GK section we are required to do 40.

The GK section was very easy, every one could tackle. Out of 50.. I was knowing 37. The technical section was bit tough most of the questions were direct and with no numerical application. Almost 30 questions were from Chemical Technology

After a month I got my result and I was declared shortlisted for the interview.

My interview was in Delhi.. My reporting was on 9 am.. first phase was the document verification and after that we were called for two interviews, one was for chemistry post and other one for production. My first interview was for chemistry.. There were 5 members sitting in front of me.. they Literally explode the questions on me.. they asked about laws of heat transfer with equations regarding final year project fision and fusion process with reactions with proper application further

some GK questions and then I was sent to other room for interview of production they asked ::
About me and my family background
about India’s fact and figures
about some conversions like 1 inch=?? cms
1 yard=?? foots
about final year project (its very important)
my willness where to join
my preferences in ONGC

One should please fully ensure in mind that specifically the chemistry and production are not different any thing could be ask.. be prepare for anything like GK like economy like future scenario of oil petrolium, oil fields, oil problems….


The paper has two sections
1. General knowledge.
2. Technical knowledge.


As I was from Industrial Engg I prepared only my subjects like operations research, quality engg, work measurement etc.. I got very few questions from these areas. The rest of the questions were from fluid mechanics and engineering materials.


Q. Alumina is the ore of…..?
a. Magnesium.
b. Aluminium.
c. Copper.
d. none.

And the major part of the questions were from Electrical engg. Almost more than 40% of the technical paper was from electrical engg syllabus. The questions were basics like what is the purpose of an induction motor, what is the diff between a transformer and a rectifier… etc.

The questions in this section were mainly from Macroeconomics (GDP, Literacy %, Economic policies) and Governance in India before independence (for example who was lord mountboton, lord wellesley, Dullhousy etc.)

Some (1or 2) of them are from biology too.

Q. What is the remarkable thing happened in the year 1919 in the context of independence fight.
a. Dandi aandolan.
b. Jalian walla baagh tragedy.
c. Quit india tragedy.
d. None.

Q. Who was the first president of Indian Muslim league?
a. Khan abdul gaffar khan.
b. Abdul razzaq.
c. Mohammad ali jinnah.
d. Aga khan 3.

Do not b too serious about the job as there is no specific syllabus for it from an engineer’s perspective. But if u crack it its ur luck. I wish u a very good luck.


There are two sections: 1) General Awareness 2) Subject Specialization. The test is of objective type except for the descriptive one.

There are 50 qts in General Awareness section out of 40 needs to be attempted. Each qt carries 1 mark. 2 are of descriptive type. Each of 5 marks. So total comes to (40×1)+(5×2)=50.

Same is the case with other section i.e. Subject Specialization. In this section there are 75 qts out of which only 60 needs to be attempted. Each qt carries 1.5 mark. 2 again are of descriptive type. Each of 5 mark. So total comes to (60×1.5)+(5×2)=100.

I am writing some of the qts I remember.

ALL THE BEST GUYS! U have to study a lot for ONGC exams bcoz it is one of the toughest paper. One cannot just go & sit for the exam w/o studying. Bcoz its useless. Study hard. Read all history, economics, current affairs, geography & basic of maths & for subjective u shud know basics of all electronics related subjects like Fibre optics, Instrumentation, ECAD, Networks, Telecommunication, etc.
