Tata Elxsi Placement Papers: Test Pattern and Sample Questions

Tata Elxsi’s online test runs on MeritTrac across three sections: 20 analytical, 20 verbal, and up to 20 role-specific technical questions, all within a 90-minute window.

The test has no negative marking and no per-section time limits. That said, sectional cutoffs exist: a strong score in two sections does not compensate for a blank third. Every section demands attention.

This article covers the full test structure, works through representative questions from each section with verified answers, and notes where legacy prep materials have circulated incorrect solutions.

Test Pattern at a Glance

The three-section structure and scoring rules, as delivered on MeritTrac:

Section	Questions	Topics
Analytical and Logical Reasoning	20	Syllogisms, Venn diagrams, data arrangements, data sufficiency, profit and loss, percentages
Verbal Ability	20	Reading comprehension, grammar, articles, sentence correction
Technical (role-specific)	10–20	Software Engineer: C/C++, DSA, OS, DBMS; Embedded Engineer: digital electronics, microcontrollers

Key rules:

• Total duration: 90 minutes
• No negative marking
• No sectional time limits (you can move between sections freely)
• Sectional cutoffs apply; leaving a section blank is a disqualifier
• Eligible branches: CSE, IT, IS, ECE, EEE
• Eligibility: 70% or above in B.Tech/B.E; 80% or above in 10th and 12th; no active backlogs

Tata Elxsi is a product and embedded engineering company, not a conventional IT services company. Its work spans automotive electronics, media, and communications design. The recruitment test reflects that: the technical section tests applied engineering knowledge specific to the role, not generic programming trivia. Freshers are hired into two primary tracks: Software Engineer and Embedded Engineer.

For comparison, the EY placement papers analytical section runs a similar logical-reasoning format, which makes cross-company prep efficient if you are targeting both companies in the same cycle.

Analytical and Logical Reasoning (20 Questions)

The analytical section draws from five topic clusters. Frequency, in rough order:

• Syllogisms (drawing conclusions from given premises)
• Data arrangements (seating, ordering, scheduling)
• Venn diagrams (set relationships, overlap counts)
• Profit and loss, percentages
• Data sufficiency

Questions are moderate in difficulty. Two minutes per question is the sustainable pace. Below are three representative sample questions with worked solutions.

Sample Question 1: Profit and Loss

• Q: An item bought for ₹400 is sold at a 20% profit. What is the selling price?
• Step 1: Profit = 20% of ₹400 = ₹80
• Step 2: Selling price = ₹400 + ₹80 = ₹480
• Answer: ₹480

Sample Question 2: Venn Diagrams

• Q: In a batch of 60 students, 35 study mathematics, 25 study physics, and 15 study both subjects. How many students study neither?
• Step 1: Students studying at least one subject = 35 + 25 − 15 = 45
• Step 2: Students studying neither = 60 − 45 = 15
• Answer: 15 students

Drawing a quick two-circle diagram and labelling the regions takes under 30 seconds and eliminates calculation errors.

Sample Question 3: Syllogisms

• Q: All managers are employees. Some employees are engineers. Which conclusion follows?
  • (a) All managers are engineers
  • (b) Some employees are managers
  • (c) All engineers are managers
  • (d) No conclusion follows
• Answer: (b) Some employees are managers
• Explanation: “All managers are employees” means every manager is also an employee, so the employee set includes all managers. Therefore “some employees are managers” is valid. The other options cannot be drawn from the given premises alone.

Verbal Ability (20 Questions)

The verbal section is reading and grammar-weighted. Topic breakdown:

• Reading comprehension (1 to 2 passages, 5 to 8 questions each)
• Grammar: articles (a, an, the), subject-verb agreement, tense
• Sentence correction and fill-in-the-blank
• Vocabulary in context

Comprehension passages are 150 to 250 words. The questions test factual recall and inference. Reading each passage once and underlining the key claims before answering saves re-reading time.

Grammar questions are typically high-accuracy for students who read English daily. Focus time here on article usage and subject-verb agreement with compound subjects. These are the most frequently tested patterns.

Sample Question: Article Usage

• Q: Choose the correct article: “She joined _____ engineering firm in Pune last month.”
  • (a) a
  • (b) an
  • (c) the
  • (d) No article
• Answer: (a) a
• Explanation: “engineering” starts with a consonant sound, so “a” is correct. “An” is used before vowel sounds, not vowel letters.

Technical Section: Software and Embedded Tracks

The technical section is the primary differentiator between candidates. The 10 to 20 questions are entirely role-specific. Two tracks exist.

Software Engineer Track

Topics: C and C++ fundamentals, pointers, memory management, data structures (arrays, linked lists, trees, stacks, queues), sorting algorithms, OS concepts (scheduling, process states), and DBMS basics.

Questions typically ask for output prediction, complexity analysis, or query output. Below is a question from legacy prep materials, with the correct answer. The version circulating on older prep sites is wrong.

Sample Question: C Switch Statement Output

• Q: What is the output of the following C program?
• Code:

  int a = 9;
  switch(a) {
      printf("hello");
      case 9: printf("abc"); break;
      default: printf("def");
  }

• Legacy (incorrect) answer: Compilation error, due to missing break after printf("hello")
• Correct answer: abc
• Explanation: The printf("hello") before the first case label is syntactically valid C. It is unreachable dead code (the switch jumps directly to the matching case), not a compilation error. Since a = 9, execution jumps to case 9, prints abc, and exits at break. Running the code confirms this. The legacy “compilation error” answer is wrong.

If you are preparing C output prediction questions, running the code yourself is faster than trusting an answer key of uncertain origin.

Embedded Engineer Track

Topics: CRO and oscilloscope operation, op-amp circuits, Boolean algebra and logic gates, microcontroller architecture (8051, ARM basics), communication protocols (UART, SPI, I2C), and digital signal processing fundamentals.

ECE and EEE students applying for this track can reference the Texas Instruments placement papers for additional embedded-electronics MCQ practice. TI tests a comparable technical depth and the preparation transfers directly.

Sample Question: CRO X-Y Mode

• Q: In X-Y mode on a CRO, two sinusoidal signals of equal amplitude are connected to the X and Y channels. The phase difference between them is 90°. The Lissajous figure displayed is:
  • (a) Circle
  • (b) Straight line
  • (c) Ellipse
  • (d) Parabola
• Answer: (a) Circle
• Explanation: With equal amplitudes A and a 90° phase difference, the parametric equations are x = A·sin(ωt) and y = A·cos(ωt), giving x² + y² = A² — a circle. If the amplitudes were unequal, the figure would be an ellipse. A straight line appears at 0° or 180° phase difference.

Preparation Strategy

A focused 4-week plan covering the full test:

Week 1: Analytical Foundation

• Complete R.S. Aggarwal “Verbal and Non-Verbal Reasoning” — chapters on syllogisms, Venn diagrams, and data arrangements
• Do 20 timed profit-and-loss problems daily. Mental calculation, not formula lookup
• Target: 18 of 20 analytical questions attempted within 25 minutes

Week 2: Verbal and Speed

• One comprehension passage daily with a 4-minute timer
• Review article and subject-verb agreement rules from Wren and Martin — ten pages maximum
• Target: 17 of 20 verbal questions attempted within 22 minutes

Week 3: Technical Track (role-specific)

Software Engineer candidates:

• Work through 30 C output-prediction MCQs. Trace execution manually on paper
• Review linked list and binary search tree operations from a standard DSA text
• OS scheduling (FCFS, SJF, Round Robin) and basic SQL queries

Embedded Engineer candidates:

• Revise Boolean algebra, Karnaugh maps, and flip-flop truth tables
• Practice 20 microcontroller architecture MCQs (8051 register map, interrupt vectors)
• CRO Lissajous figures and op-amp inverting/non-inverting circuit gain formulas

Week 4: Mock Tests and Gap Closing

• Sit two full MeritTrac mock tests (90-minute timer, no breaks)
• After each mock: list every wrong answer, trace the error to a concept gap, fix that gap
• On the last 3 days: review only. No new material

Companies in the same embedded-engineering tier run comparable test formats. If you are targeting multiple companies, preparation across the cluster transfers efficiently. The Reliance placement papers analytical section overlaps significantly with this format and doubles as a free mock bank.

The switch case question above rewards careful reading of the C specification over pattern-matching a memorised answer. That same precision matters when working with LLM-based tools in software and embedded workflows, where output behavior often diverges from what intuition predicts.
