The software companies nowadays allow all the branches to appear the recruitment process but still there some companies which allow only CS/IT branches. In SJCE college also, the placement is quite good but that depends on the company which is going to come to the campus for recruitment. There are some core companies too which conducts on campus placement in SJCE college for core branches. But the number of students getting placed in core as well as software companies from electronics and instrumentation branch is not so good. But you can still try to polish your programming skills for software companies and if you are interested in core companies, you need to have strong knowledge in core field too.

Hope this clears your doubt.
