Infosys Interview Questions for Freshers: Technical, Project and HR Answers

A fresher can memorise fifty definitions and still struggle when an interviewer starts from one resume line, asks two follow-ups, then changes tone for HR. This guide gives you representative technical, project, coding and HR questions with worked answer structures. Infosys does not publish one fixed public question list for every drive, so treat your role and call instructions as authoritative, not this article as an official paper.

Infosys interview questions: know the round before rehearsing answers

Use Infosys Interview Process: What to Prepare at Each Stage for the stage-by-stage route; here, focus on answers. Roles and drives can change the order and depth, so do not assume universal round, question or time counts. Infosys Careers says legitimate hiring includes at least one virtual or in-person interview, never requires a fee and should be authenticated through official channels.

Infosys project interview questions: defend one project under follow-ups

BookBridge is a fictional Spring Boot and MySQL library-loan API for 12,000 sample books and 1,500 sample students. The candidate owned POST /loans, validation and its transaction. Rehearse:

1. Explain the project in 90 seconds.

2. Why MySQL here?

3. What happens if two students request the last copy?

4. Describe one bug and how you isolated it.

For book_id=42, available_copies=1. Separate SELECT checks let A and B both read 1 before either writes. Instead run:

UPDATE BookCopy
SET available_copies = available_copies - 1
WHERE book_id = 42 AND available_copies > 0;

A gets affected_rows=1, commits and leaves 0. B gets affected_rows=0 and returns unavailable. Combining the check and decrement means only one request claims the copy. Explain that reasoning before naming transactions or locks.

Infosys technical interview questions: answer one more why

Given Loan(loan_id, student_id, book_id, returned_at) rows (1,101,42,NULL), (2,101,55,NULL), (3,101,63,NULL), (4,205,77,NULL), (5,205,81,'2026-07-01'), find students with at least three open loans:

SELECT student_id, COUNT(*) AS open_loans
FROM Loan
WHERE returned_at IS NULL
GROUP BY student_id
HAVING COUNT(*) >= 3;

Result: student_id=101, open_loans=3. WHERE removes returned rows before grouping; HAVING filters the computed count afterward. Test a (returned_at, student_id) index with EXPLAIN rather than declaring it universally optimal.

Infosys coding and pseudocode questions: show the trace

Prompt: return the second distinct largest value in [12, 4, 19, 19, 7] without sorting. Track (largest, second):

(-infinity,-infinity) -> (12,-infinity) -> (12,4) -> (19,12) -> (19,12) -> (19,12)

Ignore the duplicate 19; 7 changes nothing. The answer is 12, with O(n) time and O(1) space. For an empty array or one distinct value, return an optional empty result or throw a documented exception, never 0. For [-5,-2,-9], the pair ends at (-2,-5), so the answer is -5.

Infosys HR interview questions: turn claims into evidence

Prepare structures, not scripts: Tell me about yourself; Why do you want to join Infosys?; What is one strength and one weakness?; Tell me about a team disagreement; Are you open to relocation or shifts?; and What would you like to ask us? Use HR Interview Questions for Freshers: How to Answer Honestly for more practice. Keep relocation and shift answers truthful.

A 75-second model: “I am a final-year B.Tech IT student. DBMS and OOP are my strongest subjects. I built BookBridge with Spring Boot and MySQL, owned its loan transaction and fixed the last-copy race using a conditional update and affected-row check. I now seek an entry-level development role.”

For “Why Infosys?”, match one verified job-description or official-call detail to evidence from your work. Avoid “best company” and invented culture, project or growth guarantees.

Model STAR scenario, replace with true details: a four-person project lost two days to an API payload disagreement; its demo stayed on day 10. The candidate ran a 15-minute 9:30 a.m. sync for three mornings, froze bookId, studentId and dueDate in a shared Postman collection, and owned integration. It finished on day 9; the team demonstrated on day 10.

Infosys mock interview scorecard: test clarity and depth

Score direct answer, technical reason, evidence or trace and follow-up honesty from 0 to 2. Zero is missing, 1 is vague, and 2 is specific and defensible. Maximum: 8. This is KnowledgeGate's practice device, not an Infosys scoring system.

The concurrency answer scores 2 + 2 + 2 + 1 = 7/8: direct, reasoned and supported by book_id=42 plus affected-row values. Guessing the isolation level instead of verifying it loses one mark. Repeat only that weakness.

Infosys interview preparation: a seven-day, 11-hour-45-minute plan

Sum: 1:30 + 2:00 + 2:00 + 2:00 + 1:30 + 1:45 + 1:00 = 11:45. Miss a day? Keep the Day 6 mock, cut core-CS prompts from 15 to 8, and do not move all speaking practice to the final night. The Interview & Resume Preparation Course offers guided technical and HR practice plus personal review.

Infosys interview questions: the short version and next step

Know every resume line, prepare one project to follow-up depth, speak core-CS answers aloud, trace code on paper and build honest HR evidence. Use the scorecard during final practice.
