TCS Digital Questions: Quant, Verbal, and Coding (2026)

TCS Digital placement papers test three sections: Verbal Ability, Quantitative Aptitude, and Advanced Coding, routed by the NQT score that Ninja and Prime candidates also sit.

TCS Digital vs. Ninja: where the questions differ

Both tracks use the same TCS NQT (National Qualifier Test). The difference is which sections each track requires and what cut-off score routes a candidate to Digital vs. Ninja.

Track	CTC (2026)	Written sections	Live coding in test
TCS Ninja	Rs 3.5 to 3.9 LPA	Foundation only	No
TCS Digital	Rs 7.0 to 7.5 LPA	Foundation + Advanced	Yes (45 min, 2 to 3 problems)
TCS Prime	Rs 9.0 to 11.0 LPA	Foundation + Advanced	Yes (extended interview follows)

Ninja-track candidates sit only the Foundation section: 24 verbal questions, 30 reasoning questions, and 26 numerical questions in 120 minutes. No live coding in the written test. The Ninja-track pattern article covers the Foundation section in detail.

Digital-track candidates sit the Foundation section plus the Advanced section. The Advanced section adds a Programming Logic subsection and a live Advanced Coding problem. This is the section most candidates underestimate, because the quantitative questions in the Advanced section are harder than the Foundation numerical questions.

The Digital track also requires a higher CGPA cutoff, generally around 7.0, compared to 6.0 for Ninja.

Verbal ability questions

The Verbal Ability section tests grammar, comprehension, and vocabulary. Time allowed: 20 minutes for 10 to 15 questions.

Sentence correction

The most common sentence correction type tests subject-verb agreement, tense consistency, and pronoun usage.

• Q1: Identify the error: “Neither of the two candidates have submitted their forms.”

• Answer: “Neither of the two candidates has submitted their forms.”

• Explanation: “Neither” is a singular indefinite pronoun and takes a singular verb (“has”), not a plural verb (“have”).

• Q2: Identify the error: “The committee are planning to meet next week.”

• Answer: “The committee is planning to meet next week.”

• Explanation: Collective nouns like “committee,” “jury,” and “team” take a singular verb in standard usage unless the context emphasises individual members acting separately.

Reading comprehension

TCS Digital reading comprehension passages run 150 to 250 words. Expect 3 to 4 questions per passage: one main-idea question, one inference question, and one or two vocabulary-in-context questions.

Inference questions ask what the passage implies but does not state explicitly. Time management is the main challenge: allocate roughly 4 minutes per passage, read the questions first, then scan the passage for the answers.

Vocabulary

Synonym and antonym questions at TCS Digital are drawn from the GRE verbal-easy range. Words like “tenacious” (persistent), “laconic” (brief), and “ebullient” (enthusiastic) are representative examples. Familiarity with 500 to 800 high-frequency GRE words covers most of what appears.

Quantitative aptitude questions

The Quantitative Aptitude section runs 30 minutes for 10 to 15 questions. Topics that appear most often: permutation and combination, probability, work-time, algebra, and number systems. See NQT aptitude questions with solutions for the Foundation-level quant set that also overlaps with the Digital Advanced section.

Permutation and combination

• Q1: How many 3-digit numbers can be formed using the digits 1, 2, 3, 4, 5 without repetition?

• Step 1: Hundreds digit — 5 choices.

• Step 2: Tens digit — 4 remaining choices.

• Step 3: Units digit — 3 remaining choices.

• Answer: 5 x 4 x 3 = 60

• Q2: A committee of 5 must be selected from 7 men and 4 women, with at least 2 women. How many committees are possible?

• Case A (exactly 2 women): C(4,2) x C(7,3) = 6 x 35 = 210

• Case B (exactly 3 women): C(4,3) x C(7,2) = 4 x 21 = 84

• Case C (exactly 4 women): C(4,4) x C(7,1) = 1 x 7 = 7

• Answer: 210 + 84 + 7 = 301

Probability

• Q1: A bag contains 5 red balls and 3 green balls. Two balls are drawn at random. What is the probability that both are red?
• Total ways to choose 2 from 8: C(8,2) = 28
• Ways to choose 2 red from 5: C(5,2) = 10
• Answer: 10/28 = 5/14

Work and time

• Q1: 12 workers build a wall in 10 days. How many days will 15 workers take to complete the same wall, assuming equal individual productivity?
• Step 1: Total work = 12 x 10 = 120 worker-days.
• Step 2: Days for 15 workers = 120 / 15 = 8 days.

For the broader set of TCS aptitude questions including ratios, time-speed-distance, and data interpretation, that article covers the full topic range.

Advanced coding questions

The Advanced Coding section gives 45 minutes for 2 to 3 problems. TCS Digital allows C, C++, Java, and Python. Code must compile and execute correctly; pseudocode is not accepted.

Prime pairs with a fixed difference

• Q1: Given the range [4, 30], find all prime pairs where the difference is exactly 6.
• Primes in [4, 30]: 5, 7, 11, 13, 17, 19, 23, 29
• Pairs with difference 6: (5, 11), (7, 13), (11, 17), (13, 19), (17, 23), (23, 29)
• Answer: 6 pairs

Unique-digit numbers in a range

• Q1: Count how many integers in [10, 15] consist of unique digits only.
• 10 (digits 1, 0): unique
• 11 (digits 1, 1): repeated digit, excluded
• 12 (digits 1, 2): unique
• 13 (digits 1, 3): unique
• 14 (digits 1, 4): unique
• 15 (digits 1, 5): unique
• Answer: 5 (the numbers 10, 12, 13, 14, 15)

What difficulty level to expect

TCS Digital coding problems sit closer to standard DSA-course difficulty than to competitive-programming level. The constraint that makes them hard under test conditions is the 45-minute total window for 2 to 3 problems, which forces clean implementation over trial-and-error debugging.

Candidates who have practiced writing complete, compilable code across at least 30 medium-difficulty problems typically clear this section. Syntax fluency in one of the four allowed languages matters as much as algorithmic knowledge.

AI readiness and TCS Digital selection in 2026

TCS reported in March 2026 that 60% of its FY26 fresher hires are AI-skilled, up from 10 to 15% three years ago, and that it saw a 50% volume increase in Digital and Prime track hiring over that period, per TCS CHRO Sudeep Kunnumal. Separately, TCS cut total FY27 fresher intake to around 25,000, down from 44,000 onboarded in FY26. Fewer seats, higher bar on the AI dimension.

For Digital-track candidates, this has a practical consequence. The written test pattern above does not change meaningfully year to year. What the technical interview that follows the NQT now includes, for Digital-track hires, is a short layer of AI awareness questions: not advanced ML research, but practical familiarity with what a large language model does, how an API call to an AI service is structured, and what a basic prompt looks like in code.

The worked examples here prepare you for the NQT written test. Closing the AI awareness gap for the technical interview takes 30 to 60 hours of hands-on practice. That gap is what TinkerLLM at ₹299 is designed for: one weekend of building with an LLM API moves you from “I know what ChatGPT is” to showing a small working project, which is exactly the kind of evidence the Digital-track interview now rewards. For a structured path across the full AI skill stack, the AI roadmap for Indian engineers covers what to build and in what order.
