Infosys Interview Questions India 2026: Freshers & Experienced (All Rounds + Salary)

For freshers (campus drives and off-campus via InfyTQ):

Round 1: Infosys Online Assessment (95 minutes)

Section A: Reasoning Ability (15 questions, 25 min):

• Logical reasoning: analytical puzzles, visual patterns, analogies
• Difficulty: moderate to hard, time-pressured

Section B: Mathematical Ability (10 questions, 35 min):

• Quantitative aptitude: percentages, ratios, profit-loss, time-work
• Data interpretation: bar charts, pie charts, tables
• Difficulty: harder than TCS numerical section

Section C: Verbal Ability (20 questions, 20 min):

• Reading comprehension, sentence completion, error correction
• Vocabulary: synonyms, antonyms, fill-in-the-blanks

Section D: Puzzle Solving (5 questions, 15 min):

• Logic puzzles, cryptarithmetic, letter/number series with twists
• Unique to Infosys; hardest section for most candidates

Note on negative marking: Infosys online assessment has no negative marking in recent patterns: attempt all questions.

Round 2: Technical Interview (30–60 minutes)

• Programming language fundamentals (Java/Python/C++ based on your resume)
• Data structures: arrays, linked lists, stacks, queues, trees, hashing
• DBMS: SQL queries, normalisation, transactions, indexing
• OS basics: process/thread, deadlock, memory management
• Resume deep-dive: 'Tell me about your project. What was the most difficult bug you fixed?'
• 1 coding problem (paper or shared editor)

Round 3: HR Round (20–30 minutes)

• Standard HR: tell me about yourself, why Infosys, strengths/weaknesses, 5-year goal
• Situational: 'Tell me about a time you worked in a team conflict'
• Practical: location preference, shift readiness (Infosys has global delivery clients across time zones), joining timeline

InfyTQ (Infosys Talent Quest) is Infosys's online platform for learning and off-campus hiring. It matters most for off-campus candidates:

How InfyTQ works:

1. Register at InfyTQ.com with your college email
2. Complete learning modules (Java fundamentals, Python basics, data structures)
3. Attempt the InfyTQ certification exam
4. Score ≥65%: eligible for Infosys System Engineer role (₹3.6 LPA)
5. Score ≥75%: eligible for Infosys Power Programmer role (₹8 LPA)
6. Shortlisted candidates are called for the technical + HR interview

InfyTQ certification exam format:

• Duration: 3 hours
• Sections: Core Java OR Python (you choose), Data Structures, Logical Reasoning, Database Fundamentals
• 2 coding problems (mandatory; evaluated for both correctness and efficiency)
• Score is valid for 1 year

Power Programmer track (₹8 LPA vs ₹3.6 LPA): The Power Programmer track is Infosys's premium hiring stream. It requires:

• InfyTQ score ≥75%
• Both coding problems solved with at least one optimally
• Strong performance in a separate technical interview (DSA at LeetCode Medium level)
• CGPA ≥8.0 or consistent 70%+ throughout academics

For the standard vs Power Programmer comparison: the technical interview for Power Programmer is significantly harder: expect 2 coding problems at LeetCode Medium difficulty and a system design discussion.

Data Structures (most common section at Infosys):

1. 'What is the time complexity of inserting an element at the beginning of an array vs a linked list?' Array: O(n): all existing elements must shift right to make space Linked list: O(1): update the head pointer and new node's next pointer

2. 'How do you detect a cycle in a linked list?' Floyd's cycle detection algorithm (tortoise and hare): ```java boolean hasCycle(ListNode head) { ListNode slow = head, fast = head; while (fast != null && fast.next != null) { slow = slow.next; fast = fast.next.next; if (slow == fast) return true; } return false; } ```

3. 'What is the difference between BFS and DFS?' BFS (Breadth-First Search): visits nodes level by level; uses a queue; finds shortest path in unweighted graphs. DFS (Depth-First Search): goes as deep as possible before backtracking; uses a stack (or recursion); good for cycle detection, topological sort, maze solving.

SQL Questions (always asked at Infosys):

4. 'Write a query to find the department with the highest average salary.' ```sql SELECT department, AVG(salary) as avgsalary FROM employees GROUP BY department ORDER BY avgsalary DESC LIMIT 1; ```

5. 'What is the difference between a primary key and a unique key?' Primary key: uniquely identifies each row; cannot be NULL; only one per table. Unique key: ensures uniqueness; CAN be NULL (one NULL allowed per column in most DBs); multiple unique keys allowed per table.

6. 'What are indexes and when would you not use one?' An index is a data structure (usually B-tree) that speeds up SELECT queries by allowing the database to find rows without scanning the entire table. Do NOT add an index when: the table is very small (full scan is faster), the column has very low cardinality (e.g., a boolean column: index rarely helps), or the table has very high write volume (indexes slow INSERT/UPDATE/DELETE because the index must be updated).

Coding problem (paper/shared editor): Typical difficulty: Easy LeetCode. Common asks:

• Reverse a linked list
• Find the maximum element in each sliding window of size k
• Check if a binary tree is a BST
• Find all pairs in an array with a given sum

Infosys's HR round is longer and more exploratory than TCS or Wipro's. The interviewer genuinely probes your motivation and behavioural fit.

'Tell me about yourself': structure that works: 'My name is [Name] and I'm from [City]. I completed my B.Tech in [Branch] from [College] in [Year] with [CGPA/percentage]. During my degree, I worked on [one relevant project: what it did and your role in it]. I have experience with [primary language] and [secondary language/framework]. I'm now looking to start my career in software development at Infosys because [one specific reason that isn't generic: mention a specific Infosys initiative, client domain, or technology you're interested in working with]. Outside of academics, I enjoy [one genuine hobby].'

'Why Infosys specifically?': what they want to hear: Do not say: 'Because it's a reputed company.' Every candidate says this. Do say something genuine and specific:

• 'Infosys's EDGE internship programme and InfyTQ platform showed me that Infosys invests in continuous learning: that matters to me as a fresher.'
• 'I'm interested in Infosys's work with [Healthcare/Banking/Manufacturing] clients: I'd like to build software that operates at that scale.'
• 'Infosys's leadership in digital transformation consulting aligns with my long-term goal of working on enterprise-scale systems.'

Behavioural questions Infosys asks:

• 'Tell me about a team project where there was a conflict. How did you resolve it?'
• 'Describe a time when you had to learn something new quickly.'
• 'Tell me about a project that didn't go as planned. What did you do?'
• 'How do you prioritise when you have multiple deadlines?'

Use the STAR format (Situation, Task, Action, Result) for all behavioural answers. Keep each answer to 2–3 minutes.

Fresher packages: | Track | Package | |---|---| | System Engineer (standard) | ₹3.6 LPA | | System Engineer: Special Initiative | ₹4.5 LPA | | Power Programmer | ₹8 LPA | | Digital Specialist Engineer | ₹9.5 LPA |

Note: Infosys's CTC includes a variable performance bonus (10–15%). Take-home is typically 78–82% of CTC.

Experienced hires: | Role | Experience | Range | |---|---|---| | System Engineer | 2–4 years | ₹6–15 LPA | | Senior System Engineer | 4–7 years | ₹12–24 LPA | | Technology Analyst | 5–8 years | ₹18–32 LPA | | Senior Technology Analyst | 7–10 years | ₹25–42 LPA | | Technical Lead | 8–12 years | ₹30–55 LPA |

Infosys vs TCS salary comparison (freshers):

• Standard track: comparable (TCS Ninja ₹3.36 LPA vs Infosys System Engineer ₹3.6 LPA)
• Premium track: Infosys Power Programmer (₹8 LPA) is slightly higher than TCS Digital (₹7 LPA)
• The premium track gap widens at 2–5 years of experience; Infosys Digital Specialist track pays faster than TCS equivalents

Infosys onsite opportunities: Similar to TCS and Wipro: significant onsite opportunities to US, UK, Australia, Europe. Infosys operates large delivery centres in the US (Raleigh, Indianapolis, Richardson) as part of its US 'visa-free' hiring commitment. Internal transfers to onsite positions typically take 2–3 years.
