Infosys Software Engineer Interview Guide (2026): Rounds, Questions, and Prep Plan

Infosys continues to rely on a structured interview process for software engineering roles. In 2026 the flow is largely the same across its global delivery centers, though the exact mix of rounds can vary by business unit (e.g., fintech vs. cloud services). Understanding what each stage evaluates helps you allocate prep time wisely.

Recruiter Screen – The First Filter

The recruiter call is typically 15‑20 minutes and focuses on logistics and fit.

• What they ask: Your current role, why you’re interested in Infosys, and basic eligibility (notice period, work‑location preferences).
• What they evaluate: Communication clarity, motivation, and whether your profile matches the role’s seniority.
• How to ace it: Have a one‑sentence elevator pitch ready, and be explicit about what excites you about Infosys’s technology stack (e.g., their push into AI‑enabled enterprise solutions).

Technical Phone Screen – Coding Under Time Pressure

A 45‑minute video call with a senior engineer. You’ll share a code editor (often a shared IDE like CoderPad) and solve one to two problems.

• What they assess: Problem‑solving approach, coding style, and ability to verbalize thought process.
• Tips:
  1. Clarify constraints before jumping in.
  2. Speak out loud as you design the algorithm – this is where Call Assistant can help you rehearse a concise explanation.
  3. Write clean, compile‑ready code; avoid half‑finished snippets.

Onsite/Virtual Loop – The Core Evaluation

The loop usually lasts 2‑3 days (or a single 4‑hour virtual session) and includes three main categories:

1. Coding Deep Dive (2‑3 rounds)

• Format: Whiteboard or shared editor, 45‑60 minutes each.
• Focus: Depth over breadth. Expect variations like "optimize your solution for space" or "extend your algorithm to handle streaming input."
• Preparation: Practice with medium‑hard problems on platforms like LeetCode; aim for a solution that runs in O(n log n) or better.

2. System Design (1 round)

• Prompt style: Design a high‑level architecture for a real‑world service (e.g., a notification system for a banking app).
• Evaluation criteria:
  • Scalability thinking (sharding, caching).
  • Trade‑off justification (consistency vs. latency).
  • Ability to relate design choices to past experience.
• Sample answer skeleton: "When I built a logging pipeline at my previous company, I started by identifying the main throughput requirement (≈10k events/sec). I chose a Kafka backbone because it gave us ordered, durable streams, then added a Redis cache for low‑latency reads. To handle spikes, I introduced auto‑scaling consumer groups. This experience informs my choice of a message‑driven architecture for your notification service…"

3. Behavioral / Leadership (1‑2 rounds)

Infosys uses a variation of the STAR method but does not require you to label each part. Questions often probe:

• Team collaboration – "Tell me about a time you disagreed with a teammate and how you resolved it."
• Learning mindset – "Describe a technology you taught yourself and applied in a project."
• Customer focus – "Give an example of how you ensured a solution met client expectations."

When answering, anchor the story in your resume. For instance, if your resume lists “Implemented CI/CD pipeline for microservices,” start with that context, then walk through the challenge, your actions, and the impact.

Timeline and What to Expect

Delays can happen if the role is cross‑regional or if you’re interviewing for a niche technology stack. Keep your calendar flexible and confirm slots promptly.

Two‑Week Preparation Plan

Week 1 – Foundations

1. Day 1‑2: Review core data structures (arrays, linked lists, hash maps). Write one implementation of each from scratch.
2. Day 3‑4: Solve three medium‑hard coding problems each day, focusing on time‑space trade‑offs.
3. Day 5: Draft two system‑design outlines based on common services (e.g., URL shortener, chat messenger).
4. Day 6: Record yourself answering a behavioral question; listen for filler words and pacing.
5. Day 7: Rest – light reading of Infosys’s recent tech blog posts to stay current.

Week 2 – Mock Interviews & Polish

1. Day 8‑9: Pair‑program with a peer or use a mock‑interview platform. Simulate the phone screen environment.
2. Day 10‑11: Conduct a full‑length mock loop (2 coding + 1 design + 1 behavioral). Use Call Assistant to capture your spoken explanations and get instant feedback on staying on topic.
3. Day 12: Refine any weak spots identified (e.g., clarify design trade‑offs, tighten code comments).
4. Day 13: Review Infosys’s recent case studies to embed relevant terminology into your answers.
5. Day 14: Light review, set up interview logistics (quiet room, stable internet), and get a good night’s sleep.

How to Practice This

1. Schedule daily coding drills – 30‑45 minutes of solving one problem end‑to‑end, then explain the solution aloud.
2. Run a mock design session – pick a real‑world service, draw a quick diagram on paper, and narrate your choices as if interviewing.
3. Record behavioral stories – use Call Assistant or any voice recorder to rehearse, then playback to ensure you stay concise and resume‑focused.

FAQ

• Q: Does Infosys still use whiteboard coding in 2026? A: Yes, most engineering loops include a whiteboard or shared‑editor segment, though some teams have shifted to collaborative coding tools for virtual interviews.

• Q: How many coding rounds are typical for a senior engineer role? A: Senior roles often have 2‑3 coding rounds, plus a design interview. Junior roles may have only one coding round before moving to the loop.

• Q: What level of system‑design depth is expected? A: Expect to discuss high‑level components, data flow, scaling strategies, and trade‑offs. Detailed code‑level design is rarely required at the interview stage.

• Q: Can I ask about the specific tech stack used by the team? A: Yes, it’s encouraged to ask about the stack during the loop. It shows genuine interest and helps you tailor your answers.
