Hello fresh engineers,
I would like to share my interview questions over here so that others may be benefited from this firstly i finished my BE in 2000 (ECE) from Utkal university,Orissa.when i was doing my graduation i got a firm decision that i hav to get through only central govt jobs and not any privates or software .as u all know getting through central govt jobs is tedious but in ever gave up my aim.i wrote GATE -01 for my MTech and entered in to P.G.(CSE) in NIT,Rourkela,Orissa .nearly 2 yrs went off and i lost my fresher status .no privates wereready to recruit non freshers.I passed through many thorny paths.first i wrote my Bharat Electronics exam.this was my first and i cleared written but failed in Interview..
Secondly i wrote National Hydroelectric Power Corporation (NHPC)and i cleared written but failed in Interview
third i wrote TCS did not clear
but still i believed that God will shower his blessings one day.my nights went through cries.i became sleepless thinking of my future.
i realized to search a temporary one .i got a job as lecturer(ECE) in CVRaman college of engg.,BHUBANESWAR,ORISSA forRS.11000/month.This helped me a lot to refresh my subjects.
next i wrote BSNL did not clear
next i Wrote IOCL did not clear
then i wrote HPCL did not clear
then Airports exam did not clear.
finally i lost my hope & i decided that i was not fit enough to get through govt jobs. and i started to continue my lecturer job deciding to settle in that.
then i came through freshers sucess stories and my parents and my friends encouraged me a lot !" if u did not get the one u long for.dont frustrate GOD is going to give the best ".
finally it worked out & i got through INDIA'S prestigious organisation CWPRS as a Research Asst.?(Eng.). I AM IN MY Probation PERIOD AT CWPRS,PUNE .
