The Infosys software engineer interview process generally follows three stages, though the technical depth and number of rounds can vary depending on which track you are applying for: Systems Engineer (SE), Specialist Programmer (SP), or Power Programmer (PP).
  • Online Assessment (OA): A proctored, adaptive test that typically runs around 120 to 180 minutes, covering mathematical ability, analytical reasoning, pseudo code tracing, and verbal ability, alongside a coding section. Candidates who hold an InfyTQ certification or have performed well in HackWithInfy often skip this stage entirely.
  • Technical Interview(s): Usually one round for SE roles and two rounds for SP or PP tracks, conducted virtually via Infosys's internal platform or Microsoft Teams. Expect live coding problems alongside questions on OOPs, DBMS, operating systems, and computer networks.
  • HR / Managerial Interview: A shorter final round, usually around 15 to 20 minutes, focused on behavioral fit, communication, relocation flexibility, and salary discussion.
The technical content across these rounds falls into a few clear categories. Here is how to focus your preparation:
  • Data Structures & Algorithms (DSA): Coding problems focused on arrays, strings, and for higher tracks, dynamic programming and graphs.
  • Core CS Fundamentals: OOPs, DBMS, operating systems, computer networks, and SDLC concepts tested in the technical interview.
  • SQL & Databases: SQL queries, joins, normalization, and query optimization questions drawn from DBMS.
  • System Design: High-level design questions on scalability and microservices, primarily for SP, PP, and experienced hires.
  • Behavioral: HR round questions assessing communication, client value, and leadership using structured storytelling.
1. Data Structures & Algorithms (DSA)Arrays and strings account for roughly half of the coding questions at Infosys, so that is the best place to start. Classic problems like Trapping Rain Water, Merge Sorted Arrays, and Valid Anagram appear regularly across candidate reports. Working through our top 100 DSA questions will cover the bulk of what comes up in SE and SP rounds.For SP and PP tracks, expect the bar to rise considerably, with dynamic programming and graph problems entering the picture. Make sure you are comfortable with standard dynamic programming questions and graph traversal problems before your SP interview.One thing Infosys interviewers consistently flag is the ability to explain your reasoning. Be ready to answer follow-up questions like "Why did you use a HashMap here instead of an Array?" Getting the code to run is necessary but not sufficient.
2. Core CS FundamentalsInfosys puts significant weight on core computer science subjects during the technical interview. OOPs, operating systems, computer networks, and SDLC are all fair game, and candidates in 2025/2026 report that failing to explain SDLC phases is a common red flag for recruiters.For OOPs, focus on real-world examples that distinguish concepts like abstraction versus encapsulation rather than reciting definitions. Brush up on operating systems concepts and networking fundamentals to round out your preparation.Pseudo code tracing is a distinctive part of the Infosys assessment. You will be given code snippets in C, Java, or Python and asked to trace the exact output, so practice reading code carefully rather than just writing it.
3. SQL & DatabasesDBMS is one of the most heavily tested areas in Infosys technical interviews. SQL joins, normalization up to third normal form, and query optimization all come up regularly. Reviewing SQL theory is a solid starting point before your interview.A practical question like Nth Highest Salary is a good example of the kind of SQL problem you might face. Make sure you can write window functions and subqueries cleanly under time pressure.
4. System DesignSystem design questions at Infosys are mainly reserved for the Power Programmer track and experienced hires.Common prompts include designing a URL shortener and designing a notification system, with a focus on scalability, microservices, and load balancing.Practicing on a whiteboard-style tool helps you structure your thinking before the interview. Try working through problems like a URL shortener using our System Design practice tool, then explore more High-Level Design case studies to build range.If you are applying for a lateral or PP role, also revisit system design core concepts to make sure you can speak confidently about trade-offs between monolithic and microservices architectures.
5. BehavioralThe HR round at Infosys is short but not a formality. Interviewers specifically look for examples that demonstrate client value and leadership, so generic answers tend to fall flat. Structuring your answers using the STAR principle will help you stay focused and concrete.Some SP candidates in 2025 also reported a short presentation round where they were asked to prepare two slides covering their career aspirations and a technical project. Having a clear, confident narrative about your work is just as important as your coding ability for these tracks.For deeper practice on behavioral questions, the Behavioral Interview Course walks through how to build strong stories across the most common question types.
ConclusionInfosys rewards candidates who can explain their thinking clearly, not just those who get the right answer. Focus on core CS fundamentals, practice talking through your code, and have structured stories ready for the HR round. Follow the Infosys Interview Roadmap for a step-by-step plan covering every stage of the process.
