How to Prepare for Infosys SP in 30 Days

Infosys SP (Specialist Programmer) is the company's premium lateral-track role for freshers, offering a higher salary band and a faster growth curve than the standard Systems Engineer role. If your placement window is under a month away, this guide gives you a structured 30-day roadmap that covers every section of the 2026 exam and interview process.

What is Infosys SP and Why It Demands a Different Prep Strategy

The Infosys SP role is distinct from the regular Infosys Fresher/Systems Engineer track. SP candidates go through a separate, harder selection process focused on programming ability and problem-solving depth, not just aptitude. In 2026, Infosys has positioned SP hires directly into technology-facing teams, which is reflected in the difficulty of the coding rounds.

The selection process has three stages:

Stage	Format	Duration	Qualifying
Online Assessment (OA)	Aptitude + Coding	3 hours	Yes, eliminates ~60–70%
Technical Interview	DS/Algo, CS fundamentals	45–60 min	Yes
HR Interview	Fitment, compensation	20–30 min	Mostly formality

Unlike the NQT/Ninja track, there is no group discussion. The OA coding section carries much higher weight, candidates who clear the OA with both coding questions fully solved have a significantly higher conversion rate in interviews.

The Infosys SP exam pattern for 2026 has remained broadly stable since 2023, which means past papers are directly useful for preparation.

2026 SP Online Assessment, Section-Wise Breakdown

The OA has four sections. Based on verified candidate reports from the 2024 and 2025 drives:

Section	Questions	Time (approx)	Difficulty
Quantitative Aptitude	15	25 min	Medium
Logical Reasoning	10	25 min	Medium
Verbal Ability	20	35 min	Easy–Medium
Advanced Coding	2 problems	95 min	Hard

The coding section is where most rejections happen. In 2025 drives, candidates reported problems ranging from graph traversal to DP-based string problems, both at Leetcode Medium to Hard level. Full solutions with optimised time complexity are expected, not just partial/brute-force outputs.

Topic frequency analysis (based on 200+ candidate reports, 2022–2025):

Topic	Frequency in SP Coding Round
Arrays / Strings	~35% of problems
Dynamic Programming	~25% of problems
Trees / Graphs	~20% of problems
Recursion / Backtracking	~12% of problems
Miscellaneous (Math, Bit)	~8% of problems

Source: Estimated range based on verified candidate reports across 2022–2025 drives.

Week-by-Week 30-Day Preparation Plan

Week 1 (Days 1–7): Foundations and Audit

Before you start solving, know where you stand. Spend Day 1 taking a full-length mock OA under timed conditions. This tells you which sections need the most work.

Days 1–2: Full diagnostic mock + gap analysis
Days 3–5: Arrays, strings, two-pointer, sliding window, 2 problems/day on each
Days 6–7: Aptitude, number system, percentages, time-speed-distance, profit-loss (15 questions/day)

Do not skip the aptitude section assuming coding will carry you. SP candidates who score below the aptitude cutoff are eliminated before coding is even evaluated in some drives.

Review the Infosys eligibility criteria 2026 before applying, SP has stricter academic requirements (typically 65%+ throughout, no active backlogs).

---

Week 2 (Days 8–14): Core DSA + Reasoning

Days 8–10: Recursion, backtracking, binary search, 3 problems/day
Days 11–12: Stacks, queues, linked lists, focus on implementation-heavy problems
Days 13–14: Logical reasoning, seating arrangements, blood relations, syllogisms (20 questions/day timed)

At this point, aim to be solving Medium-level coding problems within 30–40 minutes. If you're taking longer, practice tracing through examples on paper first before typing code.

Use Infosys SP DSE coding questions 2026 to calibrate difficulty, SP and DSE coding rounds overlap significantly.

---

Week 3 (Days 15–21): Advanced Topics + Verbal

Days 15–17: Dynamic Programming, knapsack variants, LCS, LIS, coin change, matrix DP
Days 18–19: Trees and graphs, BFS, DFS, shortest path (Dijkstra), cycle detection
Days 20–21: Verbal ability, reading comprehension, sentence correction, para-jumbles (1 RC set/day + 15 questions)

DP is the single highest-yield topic for SP. Even getting partially through a DP problem cleanly is better than writing brute-force that times out. Learn to identify the recurrence relation before writing code.

---

Week 4 (Days 22–30): Interview Prep + Full Mocks

Days 22–24: CS fundamentals, OS (process vs thread, deadlocks, scheduling), DBMS (normalization, indexing, transactions), CN (OSI model, TCP/UDP, HTTP/HTTPS)
Days 25–26: OOPs, encapsulation, inheritance, polymorphism, abstraction with real code examples in your language of choice
Days 27–28: 2 full-length timed mock OAs back-to-back. Simulate exam conditions, no breaks, no stack overflow
Days 29–30: Mock technical interviews with a peer or mentor. Walk through your solutions aloud. Review weak areas flagged in mocks.

For technical interview patterns, Infosys interview questions 2026 covers the most asked CS fundamentals from recent drives.

Infosys SP Cutoff Trend (2022–2026 Projection)

The SP track does not publish official cutoffs, but based on candidate community data, the approximate qualifying benchmarks are:

Year	Aptitude + Reasoning (out of 25)	Verbal (out of 20)	Coding (out of 2 problems)
2022	~16–17	~13–14	1.5+ (partial credit)
2023	~17–18	~14	1.5+
2024	~18	~14–15	2 (full solutions preferred)
2025	~18–19	~15	2 (optimised solutions)
2026 (projected)	~18–19	~15	2 (optimised)

Data: Estimated range based on verified candidate reports. Actual cutoffs vary by drive and batch size.

The trend is clear, each year the bar on the coding section rises. Brute-force that passed in 2022 no longer clears the automated judge in 2025 drives. Optimised solutions with correct time complexity are the expectation now.

See the Infosys cutoff analysis 2026 page for a deeper dive including category-wise and campus-wise patterns.

Practice Questions

Common Mistakes That Cost SP Candidates the Offer

1. Skipping the aptitude section in prep. Many candidates assume coding alone will get them through. In 2025 drives, several candidates who solved both coding problems were still rejected because their aptitude score was below threshold. Both sections are independently qualifying.

2. Writing brute-force code without mentioning complexity. In the technical interview, always state the time and space complexity of your solution before the interviewer asks. It signals that you understand the trade-offs, not just the output.

3. Leaving the second coding problem blank. A partially correct solution with clear logic and a bug-free base case scores better than a blank. Always write the structure, even if the full solution isn't working, show your approach.

4. Not practising verbal under time pressure. The verbal section has 20 questions in 35 minutes. That is under 2 minutes per question. Candidates who don't practice timed verbal consistently leave 4–5 questions unattempted.

5. Generic HR answers without SP-specific reasoning. When asked "why SP over SE?", a vague answer about growth is a red flag. Reference the role's scope, direct technology work, faster project ownership, the salary differential. The Infosys SP DSE salary comparison 2026 page has the exact figures to reference in your answer.

Frequently Asked Questions

Q: Is 30 days enough to prepare for Infosys SP from scratch?

30 days is tight if you have zero DSA foundation, but realistic if you are at the stage where you can solve Easy Leetcode problems independently. The plan above front-loads the high-weight topics. If you have more time, extend Week 2 and add more DP practice, that section accounts for roughly a quarter of coding problems.

Q: What programming languages are accepted in the SP coding round?

Infosys accepts C, C++, Java, and Python in the online assessment. Python is slower in execution, which can cause TLE on tight time-limit problems. Java or C++ is recommended for competitive performance. That said, pick the language you are most comfortable with, a clean Java solution beats a buggy C++ one every time.

Q: Is there negative marking in the Infosys SP OA?

Based on 2024 and 2025 candidate reports, there is no negative marking in the SP online assessment. Attempt all aptitude and verbal questions, leaving them blank is the only way to guarantee zero on those questions.

Q: How is the SP coding section scored, is partial credit given?

Yes, partial credit is given based on test case pass rates. If your solution passes 6 out of 10 test cases, you receive proportional credit. This is why writing a correct brute-force solution for smaller inputs, even if it TLEs on large ones, is better than leaving the question blank.

Q: What is the salary for Infosys SP in 2026?

The Infosys SP CTC in 2026 is approximately ₹9–9.5 LPA (estimated range, based on verified offer letter reports). In-hand monthly take-home is typically ₹65,000–72,000 depending on HRA city tier and variable payout timing. Compare this with the SE track at ₹3.6–4.5 LPA, the SP premium is substantial. Full breakdown on the Infosys salary freshers 2026 page.

Q: Does Infosys SP hire off-campus?

Yes, Infosys runs off-campus drives for SP through InfyTQ and the official careers portal. The Infosys off campus 2026 page tracks active registration windows and eligibility cutoffs. Off-campus SP hires go through the same OA, there is no separate easier track.

Q: What CGPA is required for Infosys SP?

Infosys SP typically requires 65% or 6.5 CGPA throughout (10th, 12th, and graduation), with no active backlogs at the time of application. Some drives have required 70%+ for the SP track specifically. Check the Infosys eligibility criteria 2026 page for the latest drive-specific requirements before applying.
