THG Data Analyst interview questions & guide 2026

Our interview process is designed to evaluate both your technical proficiency and your ability to translate data into business value. While specific questions may vary depending on the team and seniority level, the following categories represent the core areas we assess.

Technical Proficiency

These questions test your foundational knowledge of data manipulation and your ability to work with real-world datasets.

• What is SQL and how have you applied it in your previous projects?
• Can you explain how different SQL joins function in practice?

Preparation at THG should be focused on demonstrating a balance between technical accuracy and business acumen. We look for individuals who can bridge the gap between complex code and executive-level strategy.

Technical Competence – We expect a strong command of SQL and data manipulation. You should be prepared to write queries under pressure and explain the logic behind your choices.

Business Insight – An effective Data Analyst at THG understands the "why" behind the data. You should be able to look at a dataset and quickly identify trends that impact revenue, customer retention, or operational costs.

Communication & Presentation – You will often need to present your findings to managers or executives. Practice distilling complex analyses into clear, actionable bullet points that highlight the impact of your work.

Cultural Alignment – We value agility, resilience, and a proactive mindset. Be ready to discuss how you have navigated ambiguity or managed competing priorities in previous roles.

The THG interview process is designed to be efficient and informative, reflecting the fast-paced nature of our business. Candidates typically navigate a series of stages that move from initial screening to technical assessment and final interviews. We prioritize clear communication and aim to keep the process moving at a steady, professional pace.

You can expect a blend of live technical assessments—often involving SQL—and practical case studies that require you to analyze a provided dataset and present your findings. The process is designed to give you a realistic preview of the day-to-day challenges faced by our analytics team, while also giving us a clear view of your problem-solving style.

The visual timeline above outlines the typical progression from your initial recruiter screen to the final presentation or cultural fit interview. Use this to pace your technical review, ensuring you are comfortable with SQL syntax and data storytelling before your later-stage assessments. Keep in mind that for more senior roles, the emphasis may shift more heavily toward your strategic experience and project management skills.

SQL and Data Manipulation

This is the bedrock of your role. We evaluate your ability to retrieve, join, and aggregate data efficiently. Strong candidates write clean, performant queries and understand how to handle edge cases in data.

• SQL Joins – Mastery of inner, left, and outer joins is essential.
• Data Cleaning – Handling null values, duplicates, and data type inconsistencies.
• Efficiency – Writing queries that are not only correct but optimized for performance.

As a Data Analyst at THG, your work is central to our operational success. You will spend your time diving into large datasets to uncover patterns that help our brand teams make better decisions. This often involves building and maintaining reporting dashboards, performing ad-hoc analysis for specific business requests, and participating in cross-functional projects that require data-backed insights.

Collaboration is a core component of this role. You will frequently work alongside engineers to ensure data integrity and with product managers to define tracking requirements for new features. You are expected to be a self-starter who can take a vague business question, translate it into a technical requirement, and deliver a comprehensive answer that drives the business forward.

We look for candidates who combine technical rigor with a pragmatic approach to problem-solving. While we value formal education in quantitative fields, we place the highest weight on your ability to apply these skills to real-world scenarios.

• Must-have skills – Advanced SQL proficiency, experience with data visualization software (e.g., Tableau, PowerBI, or Looker), and a demonstrated ability to perform quantitative analysis.
• Nice-to-have skills – Experience with Python or R for advanced analytics, exposure to cloud-based data warehouses (e.g., Snowflake, BigQuery), and prior experience in an e-commerce or retail environment.
• Experience level – We welcome applications from graduates and experienced analysts alike, provided you can demonstrate the analytical maturity required to handle our scale.
