Global Tiket Network Data Scientist interview questions & guide 2026

Our interview process is designed to evaluate your ability to apply data science principles to real-world business challenges. While questions vary by team, the following categories represent the core competencies we test.

Product Sense

These questions assess your ability to align data initiatives with user needs and business goals.

• How would you design a metric to measure the success of a new booking feature?
• A key conversion metric dropped by 5% overnight; how would you systematically diagnose the cause?

Preparation should focus on bridging the gap between theoretical knowledge and practical application. Do not simply memorize definitions; focus on how you would apply these concepts to the travel-tech industry.

Role-related knowledge – You must demonstrate mastery over SQL window functions, A/B testing frameworks, and metric drop diagnosis. Interviewers expect you to explain the "why" behind your technical choices, not just the "how."

Problem-solving ability – We look for candidates who can structure ambiguous problems. When faced with a case study, start by defining the objective, identifying the necessary data, and outlining your analytical approach before diving into specific models or queries.

Leadership & Communication – You will often be the primary interface between data and product strategy. You must be able to synthesize findings into clear, actionable insights that influence decision-makers at Global Tiket Network.

The Global Tiket Network interview loop is designed to be comprehensive yet efficient. You should expect a progression that moves from high-level behavioral alignment to deep-dive technical assessments. Our process prioritizes both your ability to write clean, performant code and your capacity to think critically about the products we build.

The initial stages focus on verifying your baseline technical skills and cultural alignment. As you progress, you will engage with cross-functional team members who will evaluate your ability to apply data science methods to our specific business domain. We value candidates who ask insightful questions about our data architecture and product goals.

The timeline above reflects a standard path, though variations may occur based on team seniority and location. Use this to pace your study; ensure you have refreshed your SQL and statistics fundamentals early, as these are foundational to both the technical assessment and the user-facing rounds.

A/B Testing and Experimentation

This is a critical pillar for a Data Scientist at Global Tiket Network. We expect you to go beyond basic p-values.

Be ready to go over:

• Experimentation pitfalls such as selection bias, network effects, and Peeking Problem.
• The importance of statistical significance versus practical significance.

As a Data Scientist, your day-to-day involves more than just modeling. You will work closely with Product Managers and Engineers to turn raw event logs into insights. You will be responsible for defining the success metrics for new travel features, running rigorous A/B tests to validate hypotheses, and maintaining the data pipelines that power our dashboards.

Collaboration is essential; you will often act as the "data conscience" of your squad, ensuring that product decisions are backed by evidence rather than intuition. Whether you are analyzing user churn patterns or optimizing our pricing algorithms, your work directly impacts the bottom line of Global Tiket Network.

A strong candidate for this role possesses a blend of technical depth and product intuition.

• Technical Skills: Proficient in SQL (including window functions), Python for data manipulation, and a strong grasp of inferential statistics.
• Experience: 3+ years of professional experience, ideally in a product-driven environment.
• Soft Skills: Ability to articulate technical findings to non-technical stakeholders and a proactive mindset for identifying new opportunities to use data.

Q: How much time should I dedicate to preparing for the SQL portion? A: Dedicate at least 30% of your technical study time to SQL. We focus heavily on data manipulation and complex querying, so practice common window functions until you can write them without hesitation.

Q: Is the technical assessment purely theoretical or practical? A: It is a mix. While you will face conceptual questions, the coding tests are designed to simulate real-world data manipulation tasks you would perform here.

Q: What is the best way to stand out during the behavioral rounds? A: Use the STAR method (Situation, Task, Action, Result) to frame your answers. Focus on the impact your work had on the business or the product.

• Think out loud: When solving case studies, articulate your thought process. This allows interviewers to understand your logic even if you reach a dead end.
• Focus on the "Why": Don't just explain your model; explain why it was the right choice for that specific business problem.
• Understand the Business: Familiarize yourself with the travel-tech landscape. Knowing how we make money helps you suggest more relevant metrics.

The Data Scientist role at Global Tiket Network offers a unique opportunity to shape the future of travel. Success in this loop requires a balanced preparation strategy: master your technical fundamentals, sharpen your product intuition, and be prepared to communicate your work with clarity and confidence.
