Want help with off-campus placement

I am a b.tech cse final year student, I took 2 year drop in my final year because of family issue and then rejoined again, but due to extended education I was not allowed to sit in most of the campus placements, I have 8.0+ CGPA, and some experience with C++, java and mern stack... I am not getting any revert from any off-campus applications, if someone can guide me on how to get a sde or full stack job.
