Then came my job experience at TATA MOTORS, why left job, goid pay, convince us, what is guarantee u will not leave Iocl.. I answered them, I  told I didnt find any scope to learn, diversity was missing their, here we have different options in Iocl. They told, we will put you to count cylinders for 2 years, I told, no issue 3rd year I will get something new..

Further, some tech questions related to RDBMS, compiler, machine language..

Now, they asked “where do you find yourself to be in the company?” I told that I had to be self confident so that I can manage man,machine,materials on my own.

Further, some questions about home, family, hobby. They were heavily impressed and said, we had not found such an interesting and talented candidate. Actually, they also got to know that i am BIT mesra University Gold medalist in Electrical.

  • Never tell, you have to do technical only. Technical and managerial both skills are required as Iocl has very less in technical especially for electrical. Don’t expose your future plans. Youu can share that if company provides opportunity for an MBA, you will do.
