How can I find companies to apply for jobs or internships, and what’s the right way to apply as a fresher?

I'm a B.Tech Computer Science student from the 2025 pass-out batch. I've applied for several internships and jobs through LinkedIn, Unstop, and the Infosys Careers page. However, I haven't received any rejection emails from some of them, and many job listings on the Infosys portal are asking for 2+ years of experience.

Honestly, it feels like a lot of the job posts on LinkedIn are just to gain followers.

Can someone suggest where I can find genuine job openings and internships for freshers? Also, where can I find off-campus drives, especially in Kerala?
