Dear vikas,
I dont know why you are so angry on ONGC where you had selected to complete your training.
You must beleave that in organisation like ONGC there are hundreds of such doctors/ scientists/ engineers who can change the shape of company in a day.
But unfortunately most of the employee may not be perfect all the time.
Also company policy do not allow them to do some thing to show a training student.
You are having experience of work at labs of ONGC.
If u get time to see the environment at the location of Core Work centre i.e. drill site, off-shore installation you will appreciate, try to understand mental status of such persons who might have worked in very hostile situation earlier presentely has been posted in Office.
ONGC is a great company looking for bright future of the nation.
Some time most of the organisations are also faces problem of incompetent persons who had got by any other means.
