They Data Analyst interview questions & guide 2026

Data Manipulation & Analysis

This area evaluates your hands-on ability to extract, clean, and analyze data. You must be comfortable with the tools of the trade and capable of handling messy, real-world datasets.

Be ready to go over:

• SQL/Python proficiency – Writing efficient queries and scripts to manipulate large datasets.
• Data Quality – How you validate data before basing strategic decisions on it.
• Visualization – Using tools like Power BI, Tableau, or Looker to make insights accessible.

Example questions or scenarios:

• "How do you handle missing or inconsistent data in a large dataset?"
• "What is your process for automating a manual reporting task?"

Stakeholder Management

This is arguably the most critical area for a Data Analyst at They. You are evaluated on your ability to push back when necessary and guide stakeholders toward data-backed decisions.

Be ready to go over:

• Influence – Persuading leadership to change strategy based on your findings.
• Storytelling – Creating a narrative that links data to commercial outcomes.
• Conflict Resolution – Handling situations where stakeholders disagree with your data.

Example questions or scenarios:

• "Tell me about a time you provided an insight that changed a business decision."
• "How do you handle a stakeholder who ignores your analytical findings?"

As a Data Analyst at They, you will act as a bridge between the technical teams—such as modelling and engineering—and the business teams. You will spend your time translating complex performance data into actionable insights that inform rate changes, risk selection, or customer journey improvements.

Your daily work will involve owning your analytical roadmap, ensuring that data initiatives align with the broader company goals. You will be expected to identify trends, opportunities, and risks, often working with large, complex datasets to provide a clear view of market dynamics. Collaboration is not optional; you will frequently work with engineering teams to improve data availability and quality to support your analytical needs.

A strong candidate for this role possesses a blend of technical mastery and commercial acumen. While you need the technical skills to perform the analysis, your ability to apply those skills to business problems is what will set you apart.

• Must-have skills – Proficiency in SQL and/or Python, experience with BI tools (Tableau, Power BI, or Looker), and a proven track record of delivering insights that drove commercial outcomes.
• Nice-to-have skills – Experience in insurance pricing or digital marketing analytics, knowledge of statistical modelling, and experience mentoring junior team members.
• Experience level – Typically, this role requires several years of commercial experience in a data-rich environment, demonstrating your ability to handle complex projects from start to finish.
