Infosys Interview Questions
Overview
Section titled “Overview”Infosys funnels most freshers through a single test (the IRT) into a standard Systems Engineer role, but a separate path - InfyTQ certification or the HackWithInfy coding contest - routes strong coders into the higher-paying Specialist Programmer/DSE track with a much harder interview.
Infosys interview process at a glance
Section titled “Infosys interview process at a glance”| Round | Duration | Focus Areas | Success Rate |
|---|---|---|---|
| IRT | 180 minutes | Aptitude, Reasoning, Coding | ~20% clear |
| Technical Interview | 30-50 minutes | Programming, Core Subjects, Projects (deeper for SP/DSE) | ~70% of IRT qualifiers |
| HR Interview | 20-30 minutes | Behavioral, Company Fit | ~90% of technical qualifiers |
IRT (Infosys Recruitment Test)
Section titled “IRT (Infosys Recruitment Test)”A 180-minute online test covering aptitude, reasoning, and a coding section. This is the steepest filter in the whole process - only around 1 in 5 candidates clear it, so time management across sections matters as much as raw accuracy.
Common questions
- Aptitude and reasoning - numerical ability, logical puzzles, data interpretation
- Coding section - 1-2 problems, typically array/string manipulation at an easy-to-medium level
- Basic programming-logic MCQs alongside the coding problems
Technical Interview (standard Systems Engineer track)
Section titled “Technical Interview (standard Systems Engineer track)”A 30-45 minute conversation mixing programming fundamentals, core CS subjects, and a detailed project walkthrough. Interviewers lean on “explain with an example” phrasing rather than pure theory recall.
Common questions
- C pointers, memory allocation (malloc/calloc), and array vs pointer differences
- Data structures - when to use an array vs a linked list, stack/queue basics
- DBMS - normalization (1NF/2NF/3NF), SQL query for the second-highest salary, joins
- OOPs - inheritance with an example, method overloading vs overriding
- A coding problem such as checking whether a string is a palindrome
Technical Interview (Specialist Programmer / DSE track)
Section titled “Technical Interview (Specialist Programmer / DSE track)”Reserved for candidates who clear HackWithInfy or score high on InfyTQ. Runs longer (45-50 minutes) and goes considerably deeper than the standard track.
Common questions
- JVM architecture and the Java collections framework hierarchy
- Time complexity of sorting algorithms; implement binary search
- Design a database schema for a given system (e.g. an e-commerce platform) and explain indexing
- Light system-design questions - how would you design a URL shortener? explain load balancing
- A DSA problem solved live on the coding portal in front of the interviewer (recent cycles require this)
Round-by-round breakdowns for both tracks are on the Infosys interview experience page.
HR Interview
Section titled “HR Interview”A closing 20-30 minute round on motivation and fit - the highest pass-through rate of the three stages, but still not a formality.
Common questions
- Tell me about yourself and why Infosys
- Are you willing to relocate to any Infosys location, including smaller campuses?
- Tell me about a project where you had to learn a new technology quickly to finish it
- Where do you see yourself in five years?
Sample answer frameworks for each of these are on the Infosys HR interview questions page.
Systems Engineer vs Specialist Programmer/DSE: two different bars
Section titled “Systems Engineer vs Specialist Programmer/DSE: two different bars”Most Infosys freshers go through the standard IRT-to-Systems-Engineer pipeline, where the technical interview tests fundamentals rather than advanced algorithms. A separate, smaller pool reaches Specialist Programmer (SP) or Digital Specialist Engineer (DSE) roles by clearing InfyTQ certification with a high score or performing well in HackWithInfy - Infosys’s own competitive-coding contest. That track’s coding bar (DP, graphs, trees, greedy problems, solved partly live under interviewer observation) and its technical interview (JVM internals, schema design, basic system design) sit well above what a standard Systems Engineer candidate needs to prepare for, and it pays meaningfully more. Know which track your score is routing you into before you decide how deep to go on DSA.
Frequently asked questions about Infosys interviews
Section titled “Frequently asked questions about Infosys interviews”What is the Infosys interview process for freshers?
Infosys hires freshers mainly through the InfyTQ / Infosys Recruitment Test (IRT): 1. IRT (180 minutes) - Aptitude, Reasoning, and Coding sections, with roughly 20% of candidates clearing it. 2. Technical Interview (30-50 minutes) - programming, core CS subjects, and project discussion, clearing around 70% of IRT qualifiers. 3. HR Interview (20-30 minutes) - behavioral fit and company motivation, clearing around 90% of technical qualifiers.
What questions are asked in Infosys interviews?
Infosys interviews cover aptitude and reasoning in the IRT, basic-to-medium coding problems and core subjects (OOP, DBMS, OS, networking) in the Technical round, and standard HR questions on relocation, career goals, and motivation for joining Infosys in the final round. Candidates on the Specialist Programmer/Digital Specialist Engineer track get noticeably deeper questions - JVM internals, system design basics, database schema design.
How many rounds are there in the Infosys interview?
Infosys typically runs 3 stages for freshers: the IRT (aptitude + reasoning + coding), a Technical Interview, and an HR Interview. Candidates who clear HackWithInfy or score high on InfyTQ certification get routed into the Specialist Programmer (SP) / Digital Specialist Engineer (DSE) track instead, which adds a harder, longer coding round.
What is the difference between Infosys Systems Engineer and Specialist Programmer (SP) / Digital Specialist Engineer (DSE)?
Systems Engineer is the standard fresher track via the IRT. SP and DSE are separate, higher-paying tracks reached through Infosys’s InfyTQ certification (a year-round learning-and-certification program) or HackWithInfy (an annual competitive coding contest) - both test 2-3 coding problems (medium-to-hard, DP/graphs/trees/greedy) in a much longer window, and in recent cycles candidates have had to solve at least one problem live in front of the interviewer.
How should I prepare for Infosys interviews?
For Infosys, practice aptitude and reasoning alongside basic-to-medium DSA for the IRT, revise core CS fundamentals (OOP, DBMS, OS, networking) for the Technical round, and prepare clear answers on relocation flexibility and why you want to join Infosys for the HR round. If you’re aiming for SP/DSE, prepare HackWithInfy-level DSA (DP, graphs, trees) since that track’s coding bar is much higher than the standard IRT.
How selective is Infosys hiring for freshers?
Selective at the first stage: roughly 20% of IRT candidates clear it. From there the funnel opens up - about 70% of IRT qualifiers clear the Technical Interview, and about 90% of those clear HR, for an overall selection rate of roughly 12-15% of total applicants.
