Kabir From Ajmer to Delhivery SDE (2026)

Landing a coveted Software Development Engineer (SDE) role at a major tech company like Delhivery is a dream for countless engineering students across India. For Kabir, a final-year B.Tech student from Ajmer, this dream became a reality with a 2026 placement offer, proving that strategic preparation and the right resources can bridge the gap between tier-2 colleges and top-tier tech careers. His journey from mastering fundamentals to cracking the Delhivery interview is a blueprint for aspiring developers.

The Foundation: Core CS Concepts and DSA

Kabir's strategy was built on a rock-solid understanding of Computer Science fundamentals. He knew that companies like Delhivery, Flipkart, and Zomato design their hiring processes to test problem-solving abilities rooted in core principles. He avoided jumping directly into advanced frameworks and focused on the basics first.

Building a Strong Theoretical Base

He utilized free, high-quality Indian educational platforms to strengthen his theory. NPTEL and SWAYAM courses on Data Structures, Algorithms, and Operating Systems provided him with structured, university-level knowledge. For quick revisions and conceptual clarity, he turned to popular YouTube channels like Gate Smashers for OS/DBMS and Jenny's Lectures for in-depth DSA explanations.

Mastering Data Structures & Algorithms (DSA)

This was the most critical part of his preparation. Kabir followed a disciplined, phase-wise approach:

1. Learn the Syntax & Basics: He started with a beginner-friendly language, choosing C++ for its STL and performance in interviews. He used freeCodeCamp's interactive tutorials and CodeWithHarry's Hindi-language C++ playlist to get comfortable.
2. Understand Data Structures: He methodically learned Arrays, Linked Lists, Stacks/Queues, Trees, and Graphs. For each, he focused on implementation, standard operations, and time/space complexity.
3. Practice Relentlessly: He solved over 500 problems on platforms like LeetCode and GeeksforGeeks. He followed curated lists from Striver (takeUforward)'s famous SDE Sheet, which categorizes problems by difficulty and company.

The Practical Edge: Projects and Development Skills

Understanding that a good resume needs more than just DSA prowess, Kabir built a portfolio of practical projects. He aimed for projects that solved real-world problems, similar to the logistics and scale challenges faced by companies like Delhivery and Swiggy.

• A Logistics Tracker Prototype: A web app that simulated package tracking with real-time status updates, using Node.js, React, and a mock database.
• E-commerce Microservices Demo: A simplified backend system demonstrating product catalog, user cart, and order services, built to understand scalable architecture.
• API Integration Tool: A tool that aggregated public APIs (like weather, postal codes) to showcase his ability to work with external data sources.

He hosted all his projects on GitHub with clean documentation, ensuring recruiters could easily see his code quality and development process. He supplemented his learning with free courses on Coursera (using Financial Aid) for backend development and cloud basics, and followed Apna College for full-stack project tutorials.

Cracking the Delhivery Interview Process

Kabir's preparation was put to the test through Delhivery's multi-stage interview process, which is typical for major Indian product-based companies.

The Online Assessment (OA)

The first hurdle was a coding test featuring a mix of:

• Medium-to-Hard DSA Problems: Typically 2-3 questions involving arrays, strings, and graph algorithms.
• CS Fundamentals MCQs: Questions on DBMS, OS, and basic networking concepts.

Kabir's extensive practice on timed platforms helped him manage the pressure and efficiently solve the problems.

The Technical Interview Rounds

He faced three technical rounds, each with increasing depth.

1. Round 1 (DSA & Problem-Solving): Interviewers presented a real-world scenario loosely based on logistics optimization. Kabir was asked to design an algorithm, discuss approaches, and write clean, efficient code on a shared editor. He focused on communicating his thought process clearly before coding.
2. Round 2 (System Design & Fundamentals): This round tested his ability to design scalable systems. He was asked a question like "How would you design a simplified version of a shipment allocation system?" He discussed low-level design (LLD), involving classes, relationships, and design patterns, and touched upon high-level components, databases, and APIs.
3. Round 3 (In-depth CS & Project Discussion): Here, the interviewers dove deep into his resume. They picked his logistics tracker project and asked detailed questions about his technology choices, database schema, how he would handle increased load, and trade-offs he considered. They also asked conceptual questions about OS (threads vs. processes) and DBMS (indexing, transactions).

The HR & Cultural Fit Round

The final round assessed his motivation, communication skills, and alignment with Delhivery's fast-paced, problem-solving culture. Questions revolved around his journey, challenges in projects, understanding of Delhivery's business, and long-term career goals. Kabir's genuine interest in the logistics domain and his clear articulation of his learning path made a positive impression.

Key Strategies That Made the Difference

Kabir's success wasn't accidental; it was built on specific, actionable strategies.

• Consistency Over Cramming: He dedicated 3-4 hours daily to DSA and development, without fail, for over 12 months.
• Quality of Practice: He focused on understanding the "why" behind each solution, revisiting tough problems, and participating in coding contests to improve speed.
• Mock Interviews: He practiced with peers and used platforms like Pramp to simulate the interview environment, which helped reduce anxiety.
• Networking & Guidance: He connected with seniors working at companies like Accenture, HCL, and Freshworks on LinkedIn to understand industry expectations and get resume feedback.

Salary & Role Expectations for 2026

While exact figures are confidential, SDE roles at established Indian product-based companies like Delhivery, Razorpay, and Zerodha offer competitive packages, especially for candidates from campus placements. For the 2026 cohort, freshers can expect:

• Base Salary: Typically ranging from ₹12 LPA to ₹20 LPA, depending on the role, location, and candidate's performance.
• Total CTC: Often includes additional components like joining bonus, performance-linked incentives, and ESOPs, potentially pushing the total package higher.
• Growth Trajectory: These roles are known for rapid skill development and clear career progression paths into senior engineering and architecture positions within 4-5 years.

Next Steps

Kabir's story shows that with the right plan, resources, and persistence, you can build a standout profile. Your journey starts with mastering the fundamentals.

• Begin by exploring free DSA and development courses to build your core skills.
• Then, browse project-based learning paths to create a portfolio that gets you noticed.
