Tata Communications Placement Papers: Pattern and Solved Questions

Tata Communications recruits freshers into engineering and network operations roles through a written test, group discussion, and two interview rounds. Each stage narrows the field before the final offer.

What Tata Communications Actually Does

Before opening a practice paper, one clarification: Tata Communications (NSE: TATACOMM) is not TCS. TCS is Tata Consultancy Services, one of India’s largest IT services employers. Tata Communications is a separate entity entirely. It runs global digital infrastructure: internet backbone services, cloud networking, unified communications, and enterprise security products.

The Tata Communications careers portal reflects this distinction. Fresher roles cluster around network engineering, software development (Java, Python, full-stack), and technical operations. The hiring model differs from large IT service firms. Batch sizes are smaller, roles are more specialised, and the technical questions in the written test lean toward networking concepts and engineering fundamentals rather than generic IT-staffing aptitude.

This matters for how you prepare. The aptitude portion of the test is similar across corporate India. The technical section is where Tata Communications diverges.

Written Test Pattern

The written test has two broad sections. The aptitude section covers three sub-areas; the technical section tests your engineering discipline.

Section	Area	Key Topics
Aptitude	Quantitative Analysis	Percentages, ratio and proportion, LCM and HCF, time-speed-distance, profit and loss
Aptitude	Logical Reasoning	Number series, blood relations, seating arrangements
Aptitude	Verbal Ability	Sentence correction, active/passive voice, vocabulary in context
Technical	Engineering Core	Networking basics, data structures, programming logic

The test is delivered online, sometimes through an app-based platform. Confirm the exact format with your campus placement cell; the delivery mechanism has varied across batches.

For context on how online assessment platforms structure their tests, the HirePro test questions page covers timing formats and section navigation used by major corporate assessment providers.

Quantitative Aptitude: Sample Questions with Solutions

The quantitative section rewards speed. Work through each question before checking the solution.

Q1: Stadium jogging

• Three runners complete laps in 36 seconds, 48 seconds, and 63 seconds respectively. After how many seconds will all three be together at the starting point?
• Answer: Find LCM(36, 48, 63).
• Step 1: 36 = 2 x 2 x 3 x 3
• Step 2: 48 = 2 x 2 x 2 x 2 x 3
• Step 3: 63 = 3 x 3 x 7
• Step 4: LCM = 2 x 2 x 2 x 2 x 3 x 3 x 7 = 16 x 9 x 7 = 1008 seconds

Q2: Two-digit number

• The sum of two digits of a two-digit number is 15 and their difference is 3. What is the product of the two digits?
• Answer:
• Step 1: x + y = 15, x - y = 3. Add both equations: 2x = 18, so x = 9.
• Step 2: y = 15 - 9 = 6.
• Step 3: Product = 9 x 6 = 54

Q3: Saree labeled price

• A trader buys 100 sarees at Rs.450 each. He offers a 10% discount on the labeled price while selling and still earns a 20% profit. What is the labeled price per saree?
• Answer:
• Step 1: Required SP = 450 x 1.20 = Rs.540 (covers the 20% profit on cost)
• Step 2: 90% of labeled price = Rs.540 (after applying 10% discount)
• Step 3: Labeled price = 540 / 0.90 = Rs.600

Q4: Milk and water mixture

• Pure milk costs Rs.16 per litre. A milkman mixes water, sells the mixture at Rs.15 per litre, and earns a 25% profit. In what ratio does he mix milk with water?
• Answer:
• Step 1: Profit is on cost of milk used. SP = 15, profit = 25%, so CP of mixture = 15 / 1.25 = Rs.12 per litre.
• Step 2: Every litre of mixture costs Rs.12 to produce, using milk priced at Rs.16 per litre.
• Step 3: Milk fraction in mixture = 12 / 16 = 3/4. Water fraction = 1 - 3/4 = 1/4.
• Step 4: Milk : Water = 3 : 1

Logical Reasoning: Sample Questions with Solutions

The logical reasoning section tests pattern recognition under time pressure. Number series and arrangement questions appear frequently.

Q5: Number series

• Complete the series: 37, ?, 103, 169, 257, 367
• Answer:
• Step 1: Compute differences between consecutive known terms: 103 - 37 = 66, 169 - 103 = 66, 257 - 169 = 88, 367 - 257 = 110.
• Step 2: The differences form an arithmetic sequence: 22, 44, 66, 88, 110 (common gap of 22). The first difference must be 22.
• Step 3: ? = 37 + 22 = 59
• Verification: 59 + 44 = 103, 103 + 66 = 169, 169 + 88 = 257, 257 + 110 = 367. Confirmed.

Q6: Hill-climbing order

• Five boys climb a hill in a column. J follows H. R is just ahead of G. K is between G and H. Who is in second position?
• Answer:
• Step 1: K is between G and H, and J follows H. So the partial order is: G, K, H, J.
• Step 2: R is just ahead of G, so R precedes G in the column.
• Step 3: Full order from front to back: R, G, K, H, J. Second position = G

Verbal Ability: Sample Questions

The verbal section tests grammar, vocabulary in context, and sentence transformation.

Q7: Vocabulary in context

• “Vinita trained for years to accomplish tight rope walking but found it was __________, as she could not get over her fear of heights.”
  • (a) unmatched, (b) unattainable, (c) positive, (d) perfect
• Answer: (b) unattainable. Training without overcoming the prerequisite fear makes the goal unreachable, not unmatched or perfect.

Q8: Passive voice transformation

• Convert to passive voice: “He never saw it again.”
  • (a) I never saw it again, (b) It is not seen again by him, (c) It is never again seen by him, (d) It was never again seen by him
• Answer: (d) “It was never again seen by him.” The verb “saw” (simple past active) converts to “was seen” (simple past passive), retaining the adverb position.

How to Prepare for the Tata Communications Written Test

Three focused weeks covers the aptitude and verbal sections. The technical section requires separate effort specific to your engineering stream.

Week 1: Quantitative Foundations

Practice LCM/HCF, percentages, profit-and-loss, and ratio problems. Aim for 30 questions per day with a timer running. Speed matters more than method complexity at this stage.

Week 2: Logical Reasoning and Verbal

Cover number series patterns (arithmetic, geometric, and difference-of-differences as in Q5 above), blood relations, and seating arrangements. For verbal, drill active/passive transformations and vocabulary-in-context questions.

Week 3: Mixed Mock Tests and Technical Revision

Take full-length timed tests. Track where you lose time, not just where you get wrong answers. Revise networking basics (OSI model, IP addressing, subnetting) and data structures for the technical section.

Corporate aptitude tests from large Indian companies share a common format. Reviewing EY placement papers and Reliance placement papers alongside this material builds cross-company pattern recognition. The same question types rotate through many corporate drives.

Register for the drive through jobs.tatacommunications.com and track application deadlines through your college placement cell, since campus drives are batch-specific.

The LCM and ratio questions in this test are solvable with two to three weeks of deliberate practice. What takes longer is the layer beyond placement: Tata Communications runs networks and APIs that are increasingly automated with AI-driven operations tools. If you want to get ahead of that curve before joining, TinkerLLM lets you run your first working LLM experiment for ₹299, a low-stakes way to test whether AI engineering is the direction you want to take your career.
