Does it cover both LLD and HLD?

Yes — the first half focuses on low-level/object-oriented design and machine coding; the second half covers high-level distributed system design.

Is this interview-focused?

Strongly. Every topic ties to real interview patterns, with mock design rounds and structured frameworks.

Will we design real systems?

Yes — case studies include URL shortener, Netflix, Uber, and WhatsApp-style architectures.

Which roles benefit most?

SDE-2+, backend engineers, tech leads, and anyone interviewing at product-based companies.
