Hello Friends I had my ONGC test today,but it was very bad.But I would give certain suggestions so that u may not face he problem which i had. Be thorough with Electrical Technology.Generators.motors stators etc.There are 5 questions on that. There were also good no.of questions from Hydraulic machine and Production technology. Then 3 from Strength of materials.And remember the dimensional quantities.
