Why Company-Specific Prep Matters
Many students prepare for campus placements with generic aptitude books and assume that's sufficient. It's not. TCS, Infosys, and Wipro have significantly different test formats, difficulty levels, and scoring patterns. Preparing for one without understanding the differences between them leaves candidates underprepared for the specific formats they'll actually encounter.
TCS National Qualifier Test (NQT)
The TCS NQT is conducted online and consists of multiple sections: Numerical Ability, Verbal Ability, Reasoning Ability, and a Programming Logic section. The total duration is typically 90 minutes, with section-wise time limits. The test is adaptive in some components, meaning question difficulty adjusts based on your previous answers.
The Numerical Ability section covers number systems, arithmetic (percentages, profit/loss, time-speed-distance), algebra, and probability. Questions are medium difficulty but time-constrained. Practice speed above all else.
The Verbal section includes reading comprehension passages, sentence completion, grammar error identification, and vocabulary. Read English-language content daily in the months before the test — this builds the reading speed the comprehension section requires.
The Programming Logic section (if applicable to your profile) tests basic programming constructs, output prediction, and flowchart reading. You don't need to write code, but you need to read and trace it. Practice tracing code logic for common patterns: loops, conditionals, recursion.
Previous year TCS NQT papers are widely available on PrepInsta and Freshersnow. The actual test reuses question types heavily, so pattern recognition from past papers is highly effective.
Infosys Placement Test
The Infosys written test has gone through several iterations. The current format includes: Mathematical Ability (25 questions, 35 minutes), Reasoning and Logical Ability (15 questions, 25 minutes), Verbal Ability (20 questions, 20 minutes), and Puzzle Solving (5 questions, 10 minutes).
Infosys's puzzles section is distinct from most other company tests. It tests creative problem-solving with logical puzzles — these aren't solvable by formula and require genuine lateral thinking. Practice puzzle types: river crossing problems, weighing problems, truth-teller/liar problems, and distribution puzzles.
The math section leans harder than TCS. Data interpretation and advanced probability questions appear. If your quant foundation is weak, address it explicitly before the Infosys test.
Infosys InfyTQ is the company's online learning and assessment platform. Completing InfyTQ certification significantly increases your chances of being invited to the placement drive. The platform is free and worth prioritizing early in your preparation.
Wipro NLTH (National Level Talent Hunt)
Wipro NLTH includes a Written Test and an Essay section in addition to the standard aptitude and verbal components. The essay is often overlooked in preparation but is an important filter. Topics are typically current events, technology trends, or opinion prompts.
The aptitude section covers the standard topics but at a slightly lower difficulty level than TCS or Infosys. The Wipro written test is more about consistent accuracy than speed on hard problems.
Essay preparation: practice writing structured, grammatically clean 200-300 word essays on current topics. Time yourself — 10 minutes is typically the limit. Focus on having a clear position and supporting it with two or three specific points. Don't start writing without a 30-second outline.
Preparation Timeline
Start company-specific prep at least 8 weeks before the placement season at your institution begins. The first four weeks should be general aptitude (number systems, arithmetic, logical reasoning, verbal). The last four weeks should be company-specific mock tests using previous year papers for each company you're targeting.
If you're targeting all three, take at least two full-length mocks per company in the final two weeks. Score yourself and prioritize weak areas between mocks.
On the Test Day
Read section instructions carefully before starting. Time-box aggressively — if a question takes more than 90 seconds, skip it. On tests with negative marking, don't guess randomly; skip questions where you have no idea. On tests without negative marking, never leave a question blank.
