Infosys SP DSE Preparation 2026: After Applying, Coding Questions, SQL, Interview Guide (Free PDF)
Infosys SP, DSE and Systems Engineer Preparation Guide 2026, free after sign in. Infosys reopened its off campus registration for Specialist Programmer and Digital Specialist Engineer on 28 October 2026, posted 3,000 openings on 15 October (2,000 SP Trainee, 1,000 DSE Trainee, 2024 to 2026 batch, Hyderabad, Bengaluru and Delhi NCR) and said on its 23 October results call that it hired 8,000 freshers in the quarter with 20,000 plus planned for the year. This guide covers what happens after you apply and exactly what to prepare, built from 8,693 candidate comments across the 2025 and 2026 cycles, seven written interview reports, two candidate compiled question documents and the Infosys hiring video of 26 March 2026. Part A decodes the career portal statuses (in progress, shortlisted after screening, decision pending, offer released), the twelve mails in the order they arrive, the 2026 calendar from the 4 January online assessment to the 12, 22, 29 November and 6 December in person slots, the exam as candidates sat it (3 questions in 3 hours with 12 hidden test cases, a 70 percent cut off seen on the portal, an in person round of 3 to 4 problems and a same day interview), the students reported score to role rules (1 to 1.5 solved for DSE, 2 for an interview call, 3 for the SP track) and the waits between rounds. Part B gives six coding patterns with 26 reported problems and worked Python: arrays and prefix sums, sliding window and two pointers, dynamic programming including the 25 October subarray versus subsequence lesson, graphs and backtracking, strings and greedy, binary search on the answer in the style of the official mock. It adds the small programs asked on paper, nine SQL queries with answers (second highest salary, N th salary, customers who never ordered, three table joins, deduplication with ROW_NUMBER, manager of the manager, HAVING, transactions) and the interview bank by topic: OOP and Java, DBMS, operating systems, networks, SOLID, the URL shortener, your project line by line, cloud, ML and HR. Part C puts Systems Engineer, DSE and SP L1 to L3 side by side, covers the SE campus test with pseudocode traces and the puzzles that repeat, gives a 14 day plan to the in person round and lists plainly what nobody official has confirmed: the cut off per question, the DSE versus SP line, the cooling period, result and offer timelines. Every line is labelled Infosys said it, students said it, or confirm nahi.

Frequently Asked Questions about Infosys SP DSE SE
Is this guide really free?
Yes. Create a Classic Profile account or sign in, and the full 25 page PDF opens in your browser with a download button. There is no payment and no paid edition.
Why do I have to sign in?
So the guide reaches you as a person and not a scraper, and so the next edition can reach the same account when the November and December rounds add new questions.
Where do the questions come from?
From candidates who sat the online assessment, the in person round and the interviews between January 2025 and October 2026, from two candidate compiled question documents, from seven written interview reports and from the Infosys hiring video of 26 March 2026. Every problem carries the date and round it was reported in. Nothing in the guide is an Infosys paper.
Does it cover Systems Engineer as well as SP and DSE?
Yes. The role matrix puts SE, DSE and SP L1 to L3 side by side, and a separate chapter covers the SE campus test: the five sections, pseudocode traces and the puzzles that repeat.
What does confirm nahi mean in the guide?
It marks what nobody official has published: the cut off per question, the DSE versus SP score line, the cooling period after a rejection, result and offer timelines. The guide gives what candidates report and says plainly that Infosys has not confirmed it.
Will there be a paid complete edition?
Not today. If one comes it will be announced on this page. The free edition is the full guide, not a sample.
Can I view this on mobile?
Yes. The PDF opens in the browser on any device after sign in, and you can download it to read offline.

How to Prepare for Infosys SP, DSE and SE 2026 After Applying
- Read Your Portal Status and Mails Correctly: Match the status on the career portal (in progress, shortlisted after screening, decision pending) to what candidates report it meant, and read the twelve mails in the order they arrive so a decision pending or a marksheet request is not mistaken for a rejection.
- Learn the Exam As Candidates Sat It in 2026: Online assessment of 3 questions in 3 hours with 12 hidden tests each, an in person round of 3 to 4 problems with some centres on paper, and a same day interview. Solve one question fully before the next: two with 12 of 12 beats three half done.
- Work the Six Coding Patterns and 26 Problems: Arrays and prefix sums, sliding window, dynamic programming, graphs and backtracking, strings and greedy, binary search on the answer. Each problem carries the date and round it was reported in, the approach, the complexity and worked Python. Underline contiguous or subsequence in every statement.
- Type the Nine SQL Queries and the Interview Bank From Memory: The nine queries that keep coming back, the DDL one liners, the four OOP pillars as code, the deadlock conditions, ACID with a bank example, SOLID and the URL shortener, and your project explained line by line against the resume you uploaded.
- Run the 14 Day Plan to Your Test Slot: Two hours on weekdays and four on weekends: patterns on days 1 to 10, SQL and theory on days 11 and 12, two full three hour mocks on days 13 and 14 with your own hidden tests, then the exam day rules and the list of what costs people the offer.
