Till when can I hope for campus placement?

I'm from the 2025 batch, in the electronics branch, placements are going on right now I get shortlisted only for OA and keep getting rejected for interviews, I have decent experience and projects I only want to know till when placement season would go on? And till when can I rely on campus placements? I'd appreciate it if I could get some tips on getting a tech job either on or off campus.
