Infosys Mock Test 2026: 40 Free Questions [SP, DSE, Power Programmer]

Infosys has three fresher tracks, System Engineer (SE), Specialist Programmer (SP), and Digital Specialist Engineer (DSE), and the Power Programmer pathway sits above them. The hiring exam, run on the InfyTQ / Mettl platform, is the same for all four tracks; the difference is in the cutoff. This page is a 40-question rehearsal sized to the real test.

Background: read Infosys placement papers 2026 and Infosys SP DSE coding questions before starting.

Section Pattern (2026 Cycle)

Section	Questions	Time	What it tests
Logical Reasoning	15	25 min	Puzzles, syllogism, series, blood relations
Mathematical Ability	10	35 min	Number system, percentages, time-distance
Verbal Ability	10	20 min	RC, error spotting, sentence completion
Pseudocode	5	10 min	C-style pseudo, OOP, basic data structures

Cutoffs vary by year. In 2024–25 cycles, SP candidates needed roughly 30 of 40 correct for shortlisting; SE candidates around 24 of 40. This is not an official figure, it is the median across publicly shared candidate post-mortems on Reddit, Quora, and Telegram groups. Use it as a north-star, not a guarantee.

Score Interpretation

• 34+ / 40 (85%): SP/DSE shortlist zone. Solid pseudocode and DSA fundamentals.
• 27–33 / 40 (68–82%): SE shortlist zone. Tighten Mathematical Ability gaps.
• 20–26 / 40 (50–65%): Below cutoff for most years. Restart with the Infosys SP 30-day plan.
• Below 20: Build fundamentals first using the DSA sheet and the logical reasoning shortcuts.

Two Things Most Candidates Get Wrong

1. Underestimating Verbal. Indian engineering students treat verbal as easy filler, then lose 4–5 marks to subject-verb agreement and tense errors. Spend a week on grammar drills, it is the cheapest section to improve.
2. Coding Pseudocode is not coding. It tests reading code, not writing it. Practice tracing recursion calls on paper. Most candidates fail Q39-style problems because they cannot keep a manual call stack.

For the actual coding round (post-aptitude), see Infosys SP/DSE coding questions.
