How to Prepare for Infosys

Infosys IRT is a long aptitude-heavy paper with pseudo-code and 2 coding problems. Clear sections first. HackWithInfy is a separate harder coding track for Power Programmer-style roles.

What Infosys actually tests

First round: Infosys IRT (+ HackWithInfy for premium tracks)

Time split that matches how candidates report outcomes (not a marketing pie chart):

  • Aptitude 40%
  • Coding basics 30%
  • Core CS 20%
  • HR 10%

Patterns are from student reports and vary by role and drive. Trust your college placement email over blog folklore.

Hiring flow you should prep for

Stage Time What they check
IRT ~180 min Reasoning, quant, verbal, pseudo-code, coding
Technical interview 30-45 min CS fundamentals + projects
HR 20-30 min Communication and fit

Time allocation

  • Practice Infosys IRT previous year papers with solutions
  • Focus on aptitude sections (Reasoning, Quantitative, Verbal) which carry 70 marks
  • Master coding basics - solve at least 1 coding problem correctly
  • Practice pseudo code questions in C/C++/Java/Python
  • Review core computer science subjects (DBMS, OS, OOPs, Networking)
  • Practice mock IRT tests to improve time management

Daily loop (90-120 minutes)

  1. One timed block that matches Infosys’s first round (aptitude + coding OA)
  2. Log misses: topic + why you failed (speed, concept, carelessness)
  3. Re-solve yesterday’s misses cold
  4. Twice a week: 10 minutes of resume/project narration out loud

6-8 week service-company plan

Week Focus Exit criteria
1-2 Quant + reasoning speed 2 full aptitude mocks, >70% accuracy
3-4 Verbal + programming logic / pseudo-code Comfortable under sectional timers
5-6 Coding basics + CS fundamentals 1-2 coding problems solvable cleanly
7-8 Full mocks + interview answers Sectional cutoffs cleared in mocks

Round-by-round strategy

Online Assessment

  • Sectional cutoffs matter more than a hero score in one section
  • Quant/reasoning: skip time sinks after 90-120 seconds
  • Verbal: accuracy over vocabulary flex
  • Coding/pseudo: get one clean full solve before polishing a second

Technical interview

  • OOPs, DBMS, OS, Networks - definitions plus one example each
  • Be ready to write a simple program on paper/editor
  • Project explanation: problem → your work → result (numbers if any)

HR

  • Why Infosys, gap years, location preference, bond/notice if asked
  • Speak clearly; service HR rounds fail quiet candidates more than imperfect ones

Infosys-specific drills

  • Sectional timed aptitude (aim 70%+ safe)
  • Pseudo-code tracing daily
  • At least one full coding solve under IRT constraints
  • If targeting HackWithInfy: contest-style DSA separately

Topic checklist

  • Aptitude speed with sectional accuracy
  • One coding language for basic problems
  • OOPs, DBMS, OS one-liners you can expand
  • HR answers: why company, relocation, gaps

Final stretch

30 days out: 3+ full Infosys-pattern mocks per week; build an error log by section.

7 days out: one mock every other day; revise only error-log topics; rehearse HR answers aloud.

Day before: light revision, no all-nighters - sectional exams punish fatigue.

Common mistakes for Infosys aspirants

  1. Missing sectional cutoffs or zero coding solves on IRT - fix this first
  2. Preparing only interviews while failing Infosys’s first round
  3. Collecting notes without timed mocks
  4. Listing five frameworks on the resume and defending none
  5. Changing language/stack one week before the drive
  6. Grinding LeetCode hard while failing aptitude cutoffs
