• Problem-Solving & Case Execution – dunnhumby heavily indexes on your ability to break down complex business questions. You will be evaluated on how logically you structure a problem, your data-driven approach to finding solutions, and your ability to present these solutions clearly.
• Operational Excellence & Process Design – Interviewers want to see your track record of improving efficiency. You should be prepared to discuss how you identify inefficiencies, design scalable processes, and measure success using relevant KPIs.

The interview process for an Operations Manager at dunnhumby is typically streamlined, consisting of three main stages that unfold over the course of about a month. The company moves efficiently but expects candidates to invest significant effort, particularly in the final stages. The process is designed to evaluate both your cultural fit and your practical ability to do the job.

You will typically start with a brief, high-level behavioral screen with a recruiter or HR representative. This is followed by a fit and experience interview with a Director or Hiring Manager, which often feels conversational but is highly focused on your past impact. The final and most rigorous stage is a comprehensive case study and peer interview. During this stage, you will be given a real-world business problem currently facing the team and asked to prepare a formal slide deck to present your strategic recommendations.

This visual timeline outlines the typical progression from the initial recruiter screen to the final case presentation. Use this to pace your preparation, ensuring you have foundational behavioral stories ready for the early rounds, while reserving significant time and energy to build a compelling, data-backed presentation for the final case study.

To succeed in the Operations Manager interviews, you must perform well across several distinct evaluation areas. dunnhumby uses a mix of behavioral probing and practical case work to uncover your true capabilities.

Business Acumen and Case Presentation

Because dunnhumby deals with complex retail analytics, your ability to understand the broader business context is paramount. The case study will test your strategic mindset, your ability to synthesize information, and your presentation skills. Strong candidates do not just provide an answer; they provide a structured narrative that walks the interviewers through their methodology, assumptions, and risk mitigation strategies.

Be ready to go over:

• Structuring Ambiguity – Breaking down a broad business prompt into manageable, actionable components.
• Data-Driven Decision Making – Justifying your operational recommendations with hypothetical or provided data points.
• Executive Communication – Designing clean, impactful slides and delivering a confident presentation to senior stakeholders.
• Advanced concepts (less common) – Financial modeling for operational costs, advanced capacity planning methodologies, and go-to-market operational readiness.

Example questions or scenarios:

• "Present a strategy to optimize the delivery timeline for a new suite of retail analytics products."
• "How would you structure your presentation to convince both the technical lead and the commercial director?"
• "What metrics would you track to prove your proposed operational changes were successful?"

Process Optimization and Scaling

At its core, this role is about making things work better. Interviewers will dig into your past experiences to see if you have a proven toolkit for process improvement. They want to know that you can identify root causes of friction and implement solutions that scale as the business grows.

Be ready to go over:

• Root Cause Analysis – Techniques you use to identify why a process is failing or underperforming.
• Workflow Design – How you map out current states and design optimized future states.
• Change Management – Your approach to rolling out new processes and ensuring adoption across resistant teams.

Example questions or scenarios:

• "Walk me through a time you identified a major bottleneck in your team's workflow. How did you fix it?"
• "How do you balance the need for rigorous process with the need for team agility?"
• "Describe a situation where a process you implemented failed. What did you learn?"

Stakeholder Management and Collaboration

An Operations Manager rarely acts in a vacuum. You will constantly interact with data scientists, engineers, product managers, and client leads. Your interviewers will assess your empathy, your negotiation skills, and your ability to push back professionally when necessary.

Be ready to go over:

• Cross-Functional Alignment – Getting diverse teams to agree on a single operational strategy.
• Conflict Resolution – Handling disagreements between technical constraints and commercial demands.
• Influencing Without Authority – Driving project execution when the project contributors do not report directly to you.

Example questions or scenarios:

• "Tell me about a time you had to say 'no' to a senior leader. How did you handle the conversation?"
• "How do you build trust with a highly technical team when you are focusing on operational metrics?"
• "Describe a project that required coordination across multiple time zones and departments."

This involves leading regular operational reviews, tracking project health, and intervening when deliverables are at risk.

You will collaborate heavily with Product, Engineering, and Client Delivery teams. A significant part of your role involves translating commercial requirements into operational realities, ensuring that data science models and analytics tools can be deployed efficiently to clients.
