What changed in 2026 drives
Infosys made InfyTQ certification a hard pre-requisite for SE role in 2024 - by 2026 nobody bypasses this. Power Programmer track via HackWithInfy now has 3 stages (was 2 in 2023), and Stage-3 is an onsite hackathon at Mysore DC. Specialist Programmer offers (₹9-11L) are now the realistic top-band for non-IIT/NIT candidates with strong HackWithInfy finishes.
What I'd actually study for Infosys
- 01InfyTQ Java + Python certifications - start in semester 5; certification is necessary AND insufficient (still need interview)
- 02DSA on InfyTQ platform - questions repeat across cycles; solve all listed problems before assuming you are ready
- 03HackWithInfy - register early, treat Stage-1 as a competitive programming contest, not a coding test
- 04DBMS - Infosys interviews ask schema design more than query optimisation; practice ER → relational mapping
Where most candidates trip up
Treating InfyTQ as a tutorial rather than a graded assessment. The certification carries weight in the interview itself - interviewers reference your Q-bank score. Skip the cert and you walk in with a deficit no amount of project work covers.

Last Updated: June 2026
This page is a focused practice set for the Infosys aptitude round, built around the topic mix candidates report from recent Infosys hiring cycles. Infosys is widely described as weighting logical reasoning more heavily than many peers, so this set balances quantitative and reasoning. For the exact, current pattern, section timing, and cutoffs, always confirm on the official Infosys careers portal, since these vary by role and cycle and are not always published in advance.
Infosys Aptitude: Reported Topic Map
Candidates consistently report the following spread. Treat weights as indicative and verify the current pattern on the official Infosys careers page.

Infosys Prep Plan
| Phase | Days | Focus |
|---|---|---|
| Reasoning first | 1-12 | Puzzles, seating, data sufficiency, syllogisms |
| Quantitative | 13-21 | Arithmetic, ratios, time-work, TSD, number systems |
| Verbal and mocks | 22-27 | Grammar drills plus full timed sections |
| Taper | 28-30 | Pattern revision and error-log review |
Candidates report that Infosys rewards reasoning strength most, so front-load puzzle and data-sufficiency practice. Confirm the current section timing and cutoff on the official Infosys careers portal, since these are set per cycle and are not always published in advance.
Common Mistakes In Infosys Aptitude
Candidates report a recurring set of avoidable errors in the Infosys aptitude round. Knowing them in advance protects easy marks.
- Spending too long on a single puzzle. Infosys reasoning often includes one hard puzzle that can swallow five minutes. Set a hard cap of ninety seconds per puzzle and move on; a half-solved puzzle scores zero either way.
- Misreading data sufficiency. The trap is solving the question instead of judging whether the statements are sufficient. You do not need the value, only whether it can be found. Train yourself to stop the moment sufficiency is established.
- Neglecting verbal. Strong technical candidates often under-prepare verbal and lose easy grammar and comprehension marks. The verbal section is the fastest place to bank marks with certainty.
- Skipping the formula review. Arithmetic speed depends on instant recall of percentage conversions and ratio splits. Candidates who review the formula sheet the day before report noticeably faster solving.
Topic Deep-Dive: Data Sufficiency
Data sufficiency is the Infosys-distinctive question type that trips up the most candidates. The format gives a question and two statements, and you decide which statements alone or together are enough to answer.
The disciplined method is mechanical. First, check statement one alone: can it answer the question by itself? Second, check statement two alone, deliberately forgetting statement one. Third, only if neither alone works, check both together. Never assume information that is not stated, and never compute the final value when sufficiency is already clear. The most common error is carrying information from statement one into the evaluation of statement two, which contaminates the judgment. Practicing this fixed order until it is automatic is the single highest-return drill for the Infosys reasoning section.

Frequently Asked Questions
What is the Infosys aptitude test pattern?
Candidates report the Infosys aptitude round covers quantitative ability, logical reasoning, and verbal ability, with reasoning often weighted heavily compared to other companies. Exact section counts, timing, and cutoffs vary by role and cycle, so confirm the current pattern on the official Infosys careers portal before your test.
Is Infosys aptitude harder than TCS?
Candidates frequently describe the Infosys logical reasoning section as more demanding than the typical TCS reasoning set, with more puzzles and data sufficiency. The quantitative difficulty is comparable. Treat reasoning as the section to invest the most preparation time in for Infosys specifically.
How do I prepare for Infosys reasoning?
Focus on puzzles, seating arrangement, data sufficiency, syllogisms, and logical deductions, which candidates report appearing most often. Drill these by type in timed blocks. Reasoning improves fast once you recognize the fixed patterns, so pattern practice is the highest-return activity for Infosys.
