good experience i had. heavy engineering stuffs u can enjoy. relaxed atmosphere to work mostly. senior and experienced people at work.
may not like office locations since many are in remote locations. pay revision happens only once in 10 years which doesnt look that great as you see from outside.
I applied in-person. The process took 1 day. I interviewed at Oil & Natural Gas (New Delhi (India)) in June 2012.
it was campus selection of d b.tech graduate from the collage..
