Exact exam patterns, section-wise syllabus, previous-year questions and week-by-week roadmaps for 30+ top recruiters.
TCS hires freshers through the National Qualifier Test (NQT) on TCS iON — a single integrated test with a Foundation part (Numerical, Verbal, Reasoning) and an Advanced part (Advanced Quant/Reasoning + Coding) that together decide whether you're mapped to Ninja, Digital or Prime. This guide covers the full section-wise pattern, syllabus, role-wise interview expectations, PYQ-style questions, ready code, SQL/DBMS/OOP revision and a week-by-week roadmap.
Package: ₹3.5–12 LPA
Infosys runs two distinct hiring tracks: Systems Engineer (SE) usually starts with a 100-minute aptitude, verbal, pseudocode and puzzle assessment, while Digital Specialist Engineer (DSE) and Specialist Programmer (SP) are selected mainly through a long coding assessment (typically 3 problems in 3 hours) followed by live technical interviews. 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.
Package: ₹6.25–21 LPA
Wipro hires through two closely related tracks — Elite NLTH for Project Engineers and Turbo for Junior Associate Software Engineers. Both share a similar backbone: an aptitude block covering quant, logical and verbal reasoning, a written communication (essay) task, and a two-problem coding round, followed by a technical and HR interview (sometimes with a voice/communication assessment). This guide covers the exact section split, syllabus, formulas, previous-year questions, ready-to-use code and a 6-week roadmap.
Package: ₹3.5–8 LPA
Everything you need for the Cognizant hiring process across PAN India: eligibility rules for GenC PAT (₹4 LPA), GenC Pro (₹5.4 LPA) and GenC Next (₹6.75 LPA), both reported aptitude formats, the three technical clusters (Java+SQL+Web UI, Python+SQL+Cloud, C#+SQL+Web UI), repeated coding and SQL patterns, and full technical + HR interview preparation.

Package: ₹4.5–11 LPA
Capgemini's fresher hiring for Analyst and Software Engineer runs through a shared online assessment — technical MCQs and pseudocode, an English communication test, game-based cognitive ability, a PowerSkills behavioural section and two coding problems — followed by a technical interview and an HR interview. Role and package depend on your performance across every stage, not just clearing the cutoff. This guide covers every section, the syllabus, representative questions, ready code, SQL/OOP/OS revision and a week-by-week plan.
Package: ₹4–7.5 LPA

Package: ₹30–55 LPA · intern ₹1.2–2L/mo
