How do I land my first job as a fresher?

21m about to graduate in mechanical engineering this May and core placements in my college are not looking so good, only about 10 students in my class have got offers so far. I have 9 backlogs currently so I can't apply for most of them but I've heard off campus situation is even worse. What should I be doing or where should I begin looking for to get opportunities for jobs or internships (for experience). Please help
