hi,

I assume you have mentioned your gate score, however at this score you have less chances for psus calls for interview, right now you can apply for polytechnic as well as b.tech colleges for lecturer post, also you may join some of the coaching institute where they provides lectures for competitive exam, right now if you want to do core sector work it may really difficult to find since most of the organization ants btech graduate and civil engineering works also related with field engineering. however I suggest you to apply on linkedin, naukri dot com, times job , upload your cv and mention the all skills you have.

best of luck for your future endeavor.
