Hi Naresh,

Your further steps to become a software engineer depends on what course you pursued in your undergraduation. If it was BCA you can go for MCA to become a software engineer at a reputed place. If your course had no link to software yet, you have to pursue B.tech which again is possible only if you had science in yoir 11th and 12th. Otherwise you can also go for a diploma in fields related to computer science to get average jobs in the field. 

The skills you mainly require are programming in C, C++, Python, Java etc and Debugging.

All the best!
