Query Regarding Backend Stack, DSA, System Design, Cloud

1. Beyond DSA (doing that from LC/Striver currently ), which should I prioritize more Backend, System Design, CS Fundamentals,or Cloud? especially when aiming off campus 2. Also pls suggest good free/paid resources (YT/courses) for Backend and System Design Background : 2nd yr student in India ,Tier 1 college( core branch so college doesnt even make any difference ig ) PS : am quite aware of domain-role mappings, but genuinely confused about prioritization , given the current tough market, & thus worse off-campus scenario, & AI disruption (Claude Code etc.)
