Real interview questions and answers
HR: Tell me about yourself.
Same structure as TCS — under 90 seconds, name → strongest technical area → one specific project → why Infosys. Mention InfyTQ if you've cleared it; that signals you're aware of Infosys's ecosystem.
HR: Why Infosys?
Specific is better than generic: Infosys's focus on digital services (Cobalt cloud, AI/automation), the Mysore campus training (best in industry), or the Pratham/iCode learning platforms. Avoid "great company" answers — every interviewer hears them daily.
HR: What do you know about Infosys?
Have these ready: founded 1981 by Narayana Murthy + 6 co-founders, headquartered in Bangalore, second-largest Indian IT services company by revenue, listed on NYSE and BSE, acquired companies like Lodestone and Panaya, biggest practice areas are BFSI and digital transformation.
Technical: What is a constructor in OOP?
A special method that runs automatically when an object is created. Same name as the class, no return type. Used to initialize fields. Types: default (no args), parameterized (takes args), copy constructor (takes another object of the same class). In Java, if you don't define one, the compiler creates a default no-arg constructor.
Technical: Difference between method overloading and overriding.
Overloading: same method name, different parameters (signatures), within the same class — resolved at compile time. Overriding: same method name AND same parameters, in a subclass replacing the parent's implementation — resolved at runtime via dynamic dispatch. Overloading enables polymorphism at compile time; overriding enables it at runtime.
Technical: Explain DBMS vs RDBMS.
DBMS is a generic system to store and retrieve data — could be file-based, hierarchical, etc. RDBMS is a specific type that stores data in tables with relationships, enforces constraints (primary/foreign keys), supports SQL, and provides ACID guarantees. Examples: MySQL, PostgreSQL, Oracle. Most modern applications use RDBMS.
Technical: What is the difference between Java and Python?
Java is statically typed, compiled to bytecode (JVM), more verbose, faster runtime, mostly used for enterprise/Android. Python is dynamically typed, interpreted, concise syntax, slower runtime, dominant in data science/AI/scripting. Java enforces OOP; Python supports multiple paradigms. Pick by use case, not "which is better."
Technical: Find the second largest element in an array.
Single-pass O(n) approach: track two variables — largest and secondLargest, both initialized to negative infinity. Iterate; for each element, if greater than largest, secondLargest = largest, largest = current; else if greater than secondLargest and not equal to largest, secondLargest = current. Edge case: array with duplicates of the max.
Technical: What is an exception and how do you handle it?
An exception is a runtime event that disrupts normal program flow. In Java: try-catch-finally blocks. Try contains risky code, catch handles specific exception types, finally runs regardless (used for cleanup like closing files/connections). Checked exceptions must be declared/caught; unchecked (RuntimeException) don't require declaration. Best practice: catch specific exceptions, not generic Exception.
Behavioral: Describe a time you learned a new technology quickly.
Pick something specific. Structure: what triggered the need, your learning approach (course + docs + small project), how long it took, what you built with it. Infosys interviewers care that you have a learning system, not just that you know things. End with how you'd apply this to learning at Infosys.
Behavioral: How do you handle pressure and tight deadlines?
Avoid "I work better under pressure" — clichéd. Better: "I break the work into the smallest shippable units, deliver something rough quickly, then iterate. For tight deadlines specifically, I communicate early what's realistic versus stretch, so the team can make tradeoffs together rather than discovering surprises late."
Preparation tips
- Get InfyTQ certified before applying — it's free and gives direct interview shortlisting, bypassing the assessment for many candidates.
- Infosys weights communication heavily. Practice explaining technical concepts in plain English; interviewers test clarity, not jargon.
- Pseudocode questions in the OA are tricky — practice them at PrepInsta or InterviewBit before the actual test.
- For the Mysore training context: be ready to talk about your willingness to commit to a 3-6 month residential training program.
- Always have a question prepared. Good: "What does the first project allocation typically look like for a Systems Engineer?"
Common questions about Infosys interviews
What is the InfyTQ certification and is it worth it?
InfyTQ is Infosys's free programming certification covering Python, OOP, DBMS, and DS. Clearing the certification round gives you direct interview shortlisting. Yes, absolutely worth it — many tier-2/3 candidates use this as their entry path.
How long is Infosys Mysore training?
Generally 3-6 months residential training at Mysore campus, covering technical foundations + soft skills + a track-specific specialization (Java, .NET, Cloud, etc.). Strict attendance and assessment requirements. Failure to clear training assessments can result in offer revocation.
What is the difference between Systems Engineer and Power Programmer at Infosys?
Systems Engineer (~₹3.6 LPA) is the standard fresher offer. Power Programmer (~₹9 LPA) is reserved for candidates who clear an additional coding round — usually those with strong DSA skills, ICPC/Kaggle background, or Codeforces ratings.
Does Infosys hire freshers in 2026?
Yes — though hiring volumes are lower than 2021-22 peaks. Focus is on quality (InfyTQ-certified, strong digital skills) over volume. Interview-to-offer rates are tighter; preparation matters more than ever.
