MakeMyTrip Data Scientist interview questions & guide 2026

The following questions are representative of the patterns observed in recent interview cycles. Use these to identify gaps in your knowledge, but prioritize understanding the underlying mechanics of the models and algorithms mentioned.

Data Structures and Algorithms

Focus on your ability to implement efficient solutions. While not a pure software engineering role, MakeMyTrip frequently tests your foundational coding proficiency.

• How would you implement a stack using two queues?
• Write an algorithm to reverse a linked list.

Preparation for MakeMyTrip requires a disciplined approach that balances deep technical knowledge with the ability to think like a product owner. Approach your study sessions by connecting your theoretical knowledge to the specific constraints of an e-commerce travel platform.

Technical Proficiency – You must be comfortable with both the math behind models and the code required to implement them. Ensure you can write clean, efficient Python code and have a solid grasp of SQL for data extraction.

Problem-Solving Structure – When faced with a case study, avoid jumping to a specific model. Instead, start by defining the business objective, exploring the data constraints, and then proposing a solution that accounts for scalability and latency.

Communication and Clarity – MakeMyTrip values candidates who can explain complex concepts to non-technical stakeholders. Practice articulating the "why" behind your technical decisions, ensuring your reasoning is logical and business-aligned.

The interview process at MakeMyTrip is structured to evaluate your end-to-end capabilities, from foundational coding to high-level system design. You should expect a series of four rounds that progressively increase in complexity, moving from basic technical assessments to strategic discussions with leadership.

The timeline above represents a standardized path, typically spanning from an initial technical screen to a final managerial discussion. Use this flow to pace your preparation: spend the first half of your study time on technical fundamentals and the latter half on refining your approach to case studies and behavioral scenarios.

Machine Learning Depth

Your ability to go beyond "using libraries" is critical. You are expected to understand the underlying mechanics of the algorithms you employ.

Be ready to go over:

• Model evaluation techniques – Understanding when to use Precision-Recall vs. ROC-AUC.
• Feature engineering – How to handle categorical variables and high-cardinality features.
• Productionization – Challenges in deploying models, including latency and versioning.

Example scenarios:

• "Explain how you would improve a model's performance on a specific subset of user data."
• "How do you decide between a simple heuristic and a complex neural network?"

Case Study and System Design

This area tests how you apply your knowledge to solve real-world problems faced by MakeMyTrip.

Be ready to go over:

• Scalability – Designing systems that handle millions of concurrent users.
• Metrics definition – Mapping business goals (e.g., increased booking value) to technical KPIs.
• Ambiguity management – Asking the right clarifying questions to narrow down a vague problem.

Example scenarios:

• "Design a personalized travel recommendation system for a user who has never booked with us before."
• "How would you structure a system to detect fraudulent booking patterns in real-time?"

As a Data Scientist, your primary responsibility is to bridge the gap between raw data and actionable business strategy. You will spend a significant portion of your time cleaning and processing large datasets to ensure model reliability. You will also be responsible for maintaining the lifecycle of machine learning models, from initial experimentation in notebooks to deployment in the production environment.

Collaboration is constant. You will frequently sync with the engineering team to ensure your models are integrated correctly and with the product team to ensure they align with the user journey. You are expected to be an advocate for data-driven decision-making across the organization, often presenting your findings to senior leadership to influence product roadmaps.

A competitive candidate for this position should demonstrate a blend of academic depth and practical, industry-tested skills.

• Technical Skills: Proficiency in Python, SQL, and common ML libraries (Scikit-learn, XGBoost, PyTorch/TensorFlow).
• Experience: 2+ years of experience in applying machine learning to real-world problems, preferably in e-commerce or high-scale consumer platforms.
• Soft Skills: Strong stakeholder management, ability to translate business requirements into technical tasks, and a proactive attitude toward learning.

Q: How difficult are the coding rounds? A: The coding rounds focus on standard data structures (trees, linked lists, stacks). They are generally of medium difficulty, but the expectation is that your code is optimized and written in a professional, modular style.

Q: Does the company prioritize specialized ML knowledge or generalist skills? A: MakeMyTrip values generalists who can navigate a full project lifecycle. While deep knowledge of a specific domain is a plus, you must be able to apply your skills across different parts of the platform.

Q: What is the best way to prepare for the Manager Round? A: Focus on the "STAR" method (Situation, Task, Action, Result). Be ready to discuss how you have handled conflicts, managed tight deadlines, and influenced project direction using data.

• Own your resume: Every project you list is fair game for deep-dive questions. Be prepared to explain the "why" behind every decision you made in those projects.
• Be ready for pushback: Interviewers may challenge your approach to see how you defend your reasoning. Stay calm and rely on data to support your points.
• Understand the travel domain: Familiarize yourself with the specific challenges of the travel industry, such as seasonality, user intent variations, and the high cost of customer acquisition.

The Data Scientist role at MakeMyTrip is an exceptional opportunity to work on complex, high-scale problems that have a tangible impact on the travel industry. By focusing on your technical fundamentals, refining your ability to structure ambiguous case studies, and clearly articulating your past project impacts, you can position yourself as a top-tier candidate.

Your journey to joining the team starts with rigorous, focused preparation. Use the insights provided here to guide your study, and remember that MakeMyTrip values both the "how" and the "why" of your work. We encourage you to continue refining your skills and approach your upcoming interviews with confidence.
