Infosys Interview Questions 2026: InfyTQ & Power Programmer

• Systems Engineer (SE): ₹3.6 LPA: general IT roles, aptitude-focused hiring
• Power Programmer (PP): ₹6.5 LPA: strong coders, advanced DSA required
• Digital Specialist Engineer (DSE): ₹6.5–9.5 LPA: specialized tech roles

InfyTQ certification gets you a direct interview call for SE/PP tracks: it skips the initial aptitude screen entirely.

The online test has sections:

• Quantitative Aptitude: 10 questions, 25 minutes
• Logical Reasoning: 10 questions, 25 minutes
• Verbal Ability: 10 questions, 20 minutes
• Pseudo Code / Programming: 5 questions, 10 minutes
• Coding: 2 hands-on problems, 40 minutes

For Power Programmer: Additional advanced coding round with 3 hard problems.

1. Explain OOPS concepts with real-world examples
2. What is the difference between SQL and NoSQL?
3. Explain the concept of normalization
4. What is a virtual function in C++?
5. Difference between process and thread
6. What is a REST API? How does it differ from SOAP?
7. Explain the concept of inheritance with an example
8. What is garbage collection?
9. Explain the difference between ArrayList and LinkedList
10. What is the purpose of the 'static' keyword?

Infosys interviewers prefer conceptual clarity over rote definitions.

The Infosys HR round is shorter than most candidates expect: typically twenty to thirty minutes: and the questions are genuinely predictable. What separates candidates isn't knowing the questions, it's having specific answers rather than generic ones.

"Why Infosys" is the question most people answer badly. Saying you admire its scale or its global reach tells the interviewer nothing. What works: mention a concrete initiative: Infosys Cobalt (cloud services), Topaz (AI), or Wingspan (learning platform): and connect it to what you want to build or learn. That one detail signals you actually looked.

The flexibility questions (location, technology, service agreement) should be answered directly. The 2-year service agreement is standard; treating it as a negotiation point at the HR stage reads poorly. You can revisit it internally after you've joined and established yourself, but the interview is not the moment.

For "tell me about a challenging project," avoid the reflex to pick the most technically complex thing you've done. Pick the one with the most honest story: what broke, how you figured it out, what you'd do differently. Infosys HR interviewers aren't evaluating your technical depth: that happened in the previous round. They're evaluating whether you reflect on your work.
