How to Crack the Infosys Interview 2026: Complete Preparation Guide

Track 1: Systems Engineer (SE): Starting salary ₹3.6–4 LPA. Standard fresher hiring. Least competitive technically. Infosys's mass hiring track. Main product: InfyTQ certification.

Track 2: Specialist Programmer (SP): Starting salary ₹6.25–7 LPA. Higher technical bar. Applicants must clear a more difficult coding round with medium-level DSA problems. Campus-focused recruitment at tier-2 colleges.

Track 3: Digital Specialist Engineer (DSE): Starting salary ₹9.5 LPA. Highest technical bar. Requires strong coding skills (competitive programming level). Primarily campus recruitment at IITs, NITs, and BITS. Off-campus DSE is also available through Infosys Hackathons.

InfyTQ: Infosys's online learning and certification platform. Completing InfyTQ Foundation level is a prerequisite for the SE recruitment. The platform teaches basic programming, Python, DBMS, and OOP. Completing it and performing well in the assessment fast-tracks you into the SE process.

Systems Engineer (SE) process:

1. InfyTQ certification (online, self-paced)
2. Online aptitude test: Quantitative reasoning, logical reasoning, verbal ability (similar difficulty to Wipro NLTH)
3. Pseudocode / reasoning assessment: Pattern-matching, algorithm logic without actual coding
4. HR interview: Background verification questions, career goals, relocation willingness, STAR behavioural questions

Specialist Programmer (SP) process:

1. Online coding test: 2 coding problems (medium difficulty) in 3 hours + 1 aptitude section
2. Technical interview: OOP concepts, data structures, past projects, 1–2 coding questions
3. HR interview: Same as SE track

DSE process:

1. Coding test: 3 coding problems (medium to hard) + aptitude
2. Technical interview 1: Deep DSA discussion, time/space complexity, project walkthrough
3. Technical interview 2: System design basics + advanced topics
4. HR interview

For SE track: Focus on aptitude (TCS NQT or Wipro NLTH level), basic programming (Python or Java: output-based questions), OOP fundamentals (encapsulation, inheritance, polymorphism), and SQL basics (SELECT, joins, GROUP BY).

For SP track: Medium-level LeetCode problems (arrays, strings, trees, hashmaps). OOP concepts at interview depth (design patterns basics). DBMS (ER diagrams, normalisation, SQL queries). CS fundamentals (OS: process vs thread, scheduling; networking: OSI model, HTTP basics).

For DSE track: Competitive programming background: complete at minimum NeetCode 150. System design basics. Java or C++ at a high level of fluency. Core CS: OS, networking, DBMS at deep interview level.

Most-reported topics at Infosys interviews:

• OOP: 4 pillars, abstract class vs interface, method overloading vs overriding
• SQL: write a query to find nth highest salary, self-join for manager-employee
• Data structures: reverse a linked list, detect cycle, binary search tree operations
• OS: process vs thread, deadlock conditions
• Networking: OSI model, TCP vs UDP, what happens when you type a URL

Infosys 2026 fresher packages:

• SE (Systems Engineer): ₹3.6–4 LPA (base only; PF, gratuity, bonus bring total slightly higher)
• SP (Specialist Programmer): ₹6.25–7 LPA
• DSE (Digital Specialist Engineer): ₹9.5 LPA

Note: Infosys has historically had delays in joining dates. Students placed in campus 2024 have reported waiting 6–12 months for actual joining. Factor this into your planning if you have other offers.

Career growth at Infosys: The SE track leads to Systems Engineer → Senior Systems Engineer → Technology Analyst → Technical Lead. Typical promotions take 2–3 years per level. Engineers looking for faster growth typically move to product companies after 1–2 years at Infosys.
