Overview

Interviewing for Data Scientist at Kantar

Interviewing for a Data Scientist position at Kantar is a distinct experience from applying to the same role elsewhere. Kantar with 30,000+ employees, has built a structured hiring process that reflects both the demands of the Data Scientist role and the company's own values and culture. The process is designed to assess not just whether you can do the job technically, but whether you'll thrive in Kantar's specific working environment.

For Data Scientists specifically, Kantar tends to emphasise practical problem-solving and technical depth alongside cultural fit. You should expect a process that tests your ability to work with tools like Python (NumPy, pandas, scikit-learn), Machine learning algorithms and theory, Deep learning frameworks (TensorFlow/PyTorch) in realistic scenarios, not just abstract theory. The interviewers are typically people you'd be working with directly, so the conversation goes both ways — they're evaluating you, but you're also getting a genuine sense of the team and day-to-day work.

Understanding what Kantar values — and how that translates into their interview expectations for a Data Scientist — gives you a significant advantage. This guide breaks down the full process, the specific questions you're likely to face, and how to prepare effectively.

Process

How Kantar interviews Data Scientists

Kantar's interview process for Data Scientist roles typically runs 4-8 weeks and involves 5 distinct stages. The process begins with online application and cv screening and progresses through increasingly focused assessments. Each stage is designed to evaluate different aspects of your suitability — from baseline qualifications through to cultural alignment and role-specific capability.

For Data Scientist candidates specifically, expect the technical stages to focus on your hands-on ability with Python (NumPy, pandas, scikit-learn), Machine learning algorithms and theory, Deep learning frameworks (TensorFlow/PyTorch), SQL and data querying. Kantar typically includes a practical assessment — this could be a coding challenge, a system design discussion, or a technical case study depending on the seniority level. The behavioural stages will probe your collaboration style and how you handle ambiguity, since Data Scientists at Kantar work across teams regularly.

Online application and CV screening

Tailor your application specifically for the Data Scientist role at Kantar. Highlight experience with Python (NumPy, pandas, scikit-learn), Machine learning algorithms and theory, Deep learning frameworks (TensorFlow/PyTorch) and use language that mirrors their job description. Kantar receives high volumes of applications, so a generic CV will be filtered out.

First-round interviews (case discussions and consumer insight thinking)

Prepare concrete examples of your Data Scientist work. Be ready to solve problems live — talk through your reasoning, consider edge cases, and demonstrate how you'd use Python (NumPy, pandas, scikit-learn) and Machine learning algorithms and theory.

Second-round interviews (complex cases and strategic insight)

Final round with director or senior leader on career vision

This stage assesses your strategic thinking and cultural fit at Kantar. Prepare to discuss where you see yourself in 3-5 years and how the Data Scientist role fits your career goals. Ask thoughtful questions about Kantar's direction and team structure.

Preparation

How to prepare for your Kantar Data Scientist interview

Preparing for a Data Scientist interview at Kantar requires a dual focus: you need to master the role-specific technical requirements and understand how Kantar operates as an organisation. Start by thoroughly reviewing the job description and mapping your experience against every requirement. For each skill or qualification listed, prepare a specific example from your career that demonstrates competence — ideally with quantifiable outcomes.

On the technical side, refresh your knowledge of Python (NumPy, pandas, scikit-learn), Machine learning algorithms and theory, Deep learning frameworks (TensorFlow/PyTorch), SQL and data querying. Kantar will likely test these in practical scenarios, so practice working through problems out loud. Review Kantar's tech stack or engineering blog if publicly available — understanding their technical choices helps you frame your answers in their context rather than speaking generically.

Research Kantar beyond their website: read recent news, check their Glassdoor reviews (their rating is 3.8/5), and look at what current employees say about working there. Understanding their culture helps you frame your answers authentically and ask informed questions — interviewers notice when a candidate has done their homework versus when they're winging it.
