Feeling Devastated. Fresher with no PPO and graduating this month

As the title says, feeling really devastated and less of hope for life. Feeling like I have been useless since all of time. And I can't say where I am wrong.

I have learnt Java and Backend development Even learnt the knowledge of basic LLD too Leetcode is still regular Suggestions to apply on further job portals like Naukri, Instahyre, Wellfound etc I followed Current company where I'm interning has given the signs that I won't be given PPO most likely even though I was very productive. I have projects which have been remarked as good by others of different designations Resume is single column ATS friendly I come from a Tier 2 institute

On campus is a dead ground now. Earlier it was GPA cuts, 12th board, gender cuts etc. For Off campus, which are very less to begin with, even after giving OAs completely, I'm still get ghosted. Talked with a few founders and connections, they are either looking for seniors, not freshers or just hiring interns.

What should I do?
