• Role: SDE Intern

• Batch/Year of Graduation: 2028

• Branch: IT

2. Application Process

• How did you apply? On Campus

  • Online Assessment: 25 July 2026 | Duration: 1.5 hours

  • Offer Date: Same day as interview

3. Interview Rounds

Round 1: Online Assessment (OA)

Mode: On-campus | Platform: HackerRank Desktop App | Shortlisted: 555 students across branches

Type: Coding + Development

• Format: 2 DSA questions + 1 Spring Boot debugging problem with AI assistance

  • Questions asked to me (solved in C++):

    1. Medium: Minimum cost to purchase all items using coupons, where each coupon halves an item's price using

       code

       1floor(price / 2ⁿ)

       . I used a brute-force approach and passed 12/15 test cases. The optimal approach uses a max heap/priority queue.

    2. Hard: Minimize the diameter of a tree using at most

       code

       1k

       cuts. I couldn't solve this during the OA.

    3. Spring Boot debugging problem based on a food-delivery application and delivery-fee discounts. Easy - 4/4 test cases. AI assistance was available, but the code had to be debugged independently.

Questions reported by other candidates included:

• 1. LFU cache (not LRU)

• 2. Bit manipulation HARD

• 3. Reconstruct array HARD

• 4. Similar tree / graph problems which are usually Leetcode hard level.

• Difficulty: Spring Boot was relatively easy, while the DSA section was challenging due to the time limit. Time management was important, and I had to prioritize one question over the other.

  My Experience: I honestly did not expect to qualify for the next round. The previous batch reportedly had 4 DSA questions, while this year the format changed to 2 DSA questions + 1 Spring Boot debugging problem. The unexpected development component made preparation and time management particularly important.

Round 2: Technical Round + Resume round

Duration: ~1 hour 15 minutes | Shortlisted: 38 students across branches

Type: Technical + Resume + HR + Managerial (ASKED ALL AT ONCE)

• There was no separate HR round; technical, resume, and behavioral questions were covered together. Almost every item on my resume was discussed in detail.

  • Questions I remember:

    1. General: Introduction, tech stack, strengths/weaknesses, interests and family background.

    2. Projects: architecture, API flow, database choices, contributions, design decisions

    3. OOP: overloading, overriding, inheritance, real-world/project examples

    4. DSA Question:https://leetcode.com/problems/middle-of-the-linked-list/description/ , . I was asked to explain the approach; some candidates were asked for pseudocode or code depending on the interviewer.

    5. DBMS/SQL: keys, constraints, foreign keys/CASCADE, joins, 2nd highest salary, DB design

    6. Spring Boot: REST controllers, annotations, Maven, Spring Initializr,pom.xml, service/repository architecture, REST status codes, JPA/Hibernate, JWT, debugging, and architecture of my project .

    7. Leadership, teamwork, clubs and hackathons

    8. GFG Puzzles : https://www.geeksforgeeks.org/aptitude/puzzle-3-cuts-cut-round-cake-8-equal-pieces/ , https://www.geeksforgeeks.org/aptitude/puzzle-measure-4l-using-given-3-buckets/

• Difficulty Level: Fairly manageable if your fundamentals and resume are strong.

Round 3: Technical + HR + Behavioural

Duration: ~30 minutes | Panel: 1 interviewer | Shortlisted: 15 students

DSA https://leetcode.com/problems/find-missing-elements/description/

• Projects and resume.

• DevOps: CI/CD concepts, tools used at different stages and their use cases.

• Git: Merge conflicts and how to resolve them.

• System design basics: scaling and load balancing.

• AI/LLMs: Use of ChatGPT/LLMs in development and debugging, including my reasoning process.

• Aptitude puzzle follow-ups.

Difficulty: Moderate; follow-up questions made the round more challenging.

4. Overall Experience and Tips

• Overall Interview Experience: Positive.

• What to prepare? Prepare everything mentioned on your resume. If you cannot confidently explain a technology or project, consider removing it.

• Tips for Aspirants: Attend the pre-placement talk carefully. It gives useful information about the company, role, hiring process, and what the interviewers may expect.
