The Core CS section was exactly what I needed for revision before my Wipro interview.

The company-specific sheets gave me a clear two-week plan instead of a huge list of random problems.

This guide covers the exact section-wise pattern, full syllabus with formulas, representative questions, ready code, SQL/DBMS/OOP revision and an 8-week roadmap. The official assessment email always overrides any public preparation resource, including this guide.
