Infosys is one of India's most recognised IT services companies and one of the largest employers of engineering freshers. In recent years, Infosys has restructured its hiring into multiple tracks: the main track for volume hiring and the Elite and Digital Specialist tracks for stronger technical profiles. This guide covers the complete Infosys interview process for 2026.

5 sections

Infosys fresher hiring tracks (2026):

1. InfyTQ (online registration + assessment): Any eligible engineering student can register on InfyTQ (Infosys's fresher hiring platform). After registering and completing the learning modules, candidates appear for the certification test, which is also the Infosys aptitude test. Cleared candidates advance to the interview.

2. Infosys Main Track (System Engineer / SDE): - Eligibility: 60% aggregate in 10th, 12th, and graduation; no active backlogs - Salary: 3.6-4.5 LPA CTC - Roles: System Engineer, Operations Executive

3. Infosys Elite Track (Senior Systems Engineer at joining): - Eligibility: 7.0 CGPA or above; no active backlogs - Requires clearing the Elite-track-specific assessment (higher-difficulty coding section) - Salary: 7.5-9.5 LPA CTC - Role: Senior Systems Engineer

4. Infosys Digital Specialist Track (Power Programmer / SP3): - Eligibility: 8.0 CGPA or above; strong competitive programming background - Requires exceptional performance on the coding assessment - Salary: 9-11 LPA CTC - Role: Specialist Programmer

5. InStep (Infosys global internship): - Highly selective 10-week paid internship for top students - Often leads to a PPO (Pre-Placement Offer) for the Elite or Digital track

Infosys InfyTQ / NQT assessment sections:

1. Reasoning Ability (15 questions, 25 minutes): - Logical reasoning: syllogisms, blood relations, seating arrangements - Analytical reasoning: data interpretation, logical sequences

2. Mathematical Ability (10 questions, 35 minutes): - Quantitative aptitude: time-work, percentages, profit-loss, number systems, basic probability

3. Verbal Ability (20 questions, 20 minutes): - Reading comprehension (1-2 passages), sentence completion, vocabulary, error spotting

4. Coding Section (for Elite and Digital tracks, 2 problems in 3 hours): - Languages: Python, Java, or C++ - Problem 1: LeetCode easy-medium (arrays/strings manipulation) - Problem 2: LeetCode medium (trees, graphs, or DP) - Elite track: same pattern, slight difficulty increase - Digital/SP3 track: both problems at LeetCode medium-hard; partial solutions score partial marks

Cut-off estimates (not officially published, based on candidate reports): - Main track: approximately 60-65% overall - Elite track: approximately 75-80% overall plus complete solution to at least one coding problem - Digital track: approximately 85%+ overall plus strong performance on both coding problems

Infosys technical interview question bank:

1. OOP: 'What are the four pillars of OOP?' - Encapsulation: hiding internal state via private fields and public methods - Abstraction: exposing only what is necessary (interfaces, abstract classes) - Inheritance: subclass inherits from superclass, promotes code reuse - Polymorphism: same method name, different behaviour (overloading = compile-time; overriding = runtime)

'What is the difference between abstract class and interface in Java?' - Abstract class: can have state (fields), constructors, and concrete methods; single inheritance - Interface: defines a contract; no state; Java 8+ allows default and static methods; a class can implement multiple interfaces - Rule of thumb: use interface for loose coupling; use abstract class for shared behaviour within a hierarchy

2. DBMS: 'Write a SQL query to find the second highest salary.' SELECT MAX(salary) FROM employees WHERE salary NOT IN (SELECT MAX(salary) FROM employees);

'What is normalisation?' - Eliminating data redundancy. 1NF: atomic values, no repeating groups. 2NF: 1NF plus no partial dependencies on a composite key. 3NF: 2NF plus no transitive dependencies.

3. Data Structures: 'Reverse a linked list iteratively.' prev = None; curr = head while curr: next = curr.next; curr.next = prev; prev = curr; curr = next return prev

'What is the time complexity of searching in a BST?' O(h) where h is the height: O(log n) for a balanced BST; O(n) worst case for a degenerate (skewed) BST.

Infosys HR interview questions and answers:

1. 'Tell me about yourself' (60-90 seconds): Structure: current status (final year B.Tech in CSE from [college name]) + key academic achievement or project + most relevant skill + what you are looking for at Infosys.

2. 'Why Infosys?' Research: Infosys's Springboard internal learning platform (3000+ courses, 200+ certifications), Infosys's global client delivery model, their work in AI and cloud (Cobalt cloud platform, Topaz AI suite). Specific answer: 'I want to develop expertise in cloud and AI services, and Infosys's Topaz and Cobalt platforms put them at the cutting edge of enterprise AI adoption. The Springboard learning platform also aligns with my goal of continuous learning.'

3. 'What are your strengths and weaknesses?' Strength: choose one relevant to software engineering (problem-solving, systematic debugging, quick learner). Back it with a specific example. Weakness: choose a real one with a concrete action you are taking. 'I tend to focus on getting things perfect before showing them to anyone. I have been working on this by setting internal review checkpoints earlier in the development process.'

4. 'Where do you see yourself in 5 years?' For Infosys: 'In 5 years, I see myself as a senior engineer at Infosys, contributing to complex client delivery in [your technology area: cloud, data, AI]. I want to grow into a role where I can lead a module and mentor junior engineers.'

5. 'Are you willing to relocate?' Infosys posts engineers to any of its India delivery centres (Bangalore, Hyderabad, Pune, Chennai, Mysore, Kolkata). Be prepared to say yes.

Infosys vs TCS vs Wipro vs Cognizant (for freshers in 2026):

Salary comparison- TCS Ninja: 3.86 LPA - Infosys Main: 3.6-4.5 LPA - Wipro Main: 3.5 LPA - Cognizant GenC: 4 LPA - TCS Digital: 7 LPA - Infosys Elite: 7.5-9.5 LPA - Wipro Elite: 6.5-7.5 LPA - Cognizant GenC Elevate: 9-10 LPA

If you qualify for the Elite/Digital/Elevate track at multiple companies, the salary difference is small. Choose based on project type, location, and learning culture.

Brand for future job switch: All four brands are recognised and respected when switching to a product company after 2-3 years. The brand matters less than the skills and project experience you develop.

Coding cultureCognizant GenC Elevate and Infosys Digital Specialist track have the highest technical bars among fresher IT services tracks. If you are serious about engineering, target the highest track you can qualify for.

Learning investmentInfosys's Springboard platform is generally considered the best internal learning resource among the four, with the widest course library and more structured certification paths.

Quick answers

Before you close this tab.

Infosys InfyTQ (Infosys Training and Qualification platform): InfyTQ is Infosys's proprietary fresher hiring platform that combines learning modules, certification exams, and the hiring assessment in one place. Registration: go to infytq.infosys.com and create an account with your personal email (not your college email). Registration is open throughout the year and does not require college placement cell involvement (candidates can register directly). Learning modules: after registration, complete the free learning modules on InfyTQ covering OOP, DBMS, data structures, algorithms, and programming fundamentals in Java or Python. The modules take 10-20 hours to complete but are not mandatory to take the test. Certification exam (the hiring assessment): typically held 2-4 times per year (batch cycles). The exam is the same as Infosys's campus aptitude test and is the primary filter. Sections: Reasoning Ability (15 questions, 25 min), Mathematical Ability (10 questions, 35 min), Verbal Ability (20 questions, 20 min), and Coding (2 problems, 3 hours, for Elite track). After clearing the certification: candidates who clear the assessment are eligible for the Infosys interview (technical + HR). The interview is conducted in batches, typically 4-8 weeks after the assessment. Offer letter: after clearing the interview, Infosys issues an offer letter with a tentative joining date (which can be 6-12 months after the offer, depending on the batch intake requirements). Important: do not spam Infosys HR with joining date follow-ups. Infosys's mass hiring cycle means batch joining dates are determined by business requirements, not individual preference.

Best programming language for Infosys coding assessment: Infosys accepts Python, Java, and C++ for the coding section. Recommendation: use Python if you are comfortable with it. Python advantages in the Infosys coding assessment: (1) Less boilerplate: a Python solution is typically 30-50% shorter than the equivalent Java solution, reducing the time to write and the risk of syntax errors under pressure. (2) Built-in data structures: Python's list, dict, set, and collections module (deque, Counter, defaultdict) handle most coding problems without implementing data structures from scratch. (3) Readable: easier to debug under exam pressure. When to choose Java: if you know Java significantly better than Python (you have been using it for 2+ years in coursework or projects), use Java. A fluent Java solution beats a stumbling Python solution. When to choose C++: only if you are a competitive programmer with strong C++ skills. The STL (Standard Template Library) is powerful, but C++ error messages under time pressure are more difficult to debug than Python. Topics to prepare in your chosen language: read from stdin and write to stdout (Infosys uses a custom online judge, not LeetCode; input parsing is your responsibility), implement basic sorting and searching without library calls (some Infosys problems test this explicitly), string manipulation (split, join, replace, find).
