HI ! ARJUN

Your marks is quite good.With this score you can easily pursue mtech degree courses in older IITs(IIT DELHI,IIT KANPUR,IIT BOMBAY,IIT MADRAS,IIT GUWAHATI).But right now I cannot assure you about PSUs call letter this year paper is relatively easy as compare to last five years.Usually candidate with this marks get call letter from various PSUs.But this year cuttoff of various may go high.But you can expect PSUs.Wait till IIT Guwahati release gate score.

You can ask if you have any other queries.

GOOD LUCK!
