I am expecting 68 marks in Gate CSE 2019. In which PSUs should I apply?

In India, there are some of the really good PSUs for CSE like Bhabha Atomic Research Centre(BARC) and Indian Oil Corporation Limited(IOCL).

The cutoff for PSUs from CSE or electronics is a bit higher than the marks you have scored. The previous year it was about 70 marks for BARC and was about 82 marks in NTPC for 2017 GATE.

I can't totally deny your chances of getting any jobs at PSUs as GATE haven't released the official result and cutoffs yet. I hope you get what you are looking for.

Good luck for the results.
