Preparing for an interview at Team Lewis requires a balanced approach. You must demonstrate that you can execute the technical aspects of the role while thriving in a fast-paced agency environment that demands client-facing confidence.

Role-Related Knowledge – You must show a deep understanding of modern tracking, attribution, and analytics platforms. Be ready to discuss specific tools like Google Analytics, Google Tag Manager, paid media dashboards, and Excel in detail.

Problem-Solving Ability – Agency life is filled with ambiguous client requests. You need to demonstrate how you break down complex marketing problems, form hypotheses, and structure your analysis to find actionable solutions.

Communication and Presentation – At Team Lewis, data is only as good as the story you tell with it. You will be evaluated on your ability to present insights clearly, write professional content, and defend your strategic recommendations under questioning.

The interview process for the Marketing Analytics Specialist position at Team Lewis typically spans two to three weeks, though it can vary slightly by office location and team. The process is designed to test your cultural fit, technical capabilities, and presentation skills through a series of structured stages.

You will start with a standard phone screening with a talent acquisition representative to cover your background and interest in the agency. Following a successful screen, you will move into a series of interviews with hiring managers and directors, which may include a deep dive into your technical skills. The final stages of the process heavily emphasize practical application, requiring candidates to complete a take-home assignment, a writing sample, or a comprehensive campaign presentation.

The visual timeline above outlines the typical progression of stages from your initial application to the final offer. Candidates should use this roadmap to pace their preparation, ensuring they dedicate sufficient time to both the conversational rounds and the intensive practical assignments. While the early rounds focus on your alignment with the role, the latter half of the process is highly focused on demonstrating your actual work product.

To excel in the Team Lewis hiring loop, you must understand the specific areas where you will be evaluated. The agency looks for a combination of hard analytical skills and creative communication.

Analytical Execution & Excel

The core of your day-to-day work involves handling large datasets from various marketing channels. You must prove that you can manipulate, clean, and interpret this data accurately.

Be ready to go over:

• Data Manipulation – Advanced Excel techniques including VLOOKUP, XLOOKUP, INDEX/MATCH, and pivot tables.
• Data Cleaning – How to handle missing, duplicate, or inconsistent tracking data from multiple platforms.
• Reporting Automation – Experience setting up automated dashboards using tools like Looker Studio or Power BI.
• Advanced concepts (less common) – SQL queries for database management, basic Python or R for data analysis, and API integrations for custom reporting.

Example scenarios:

• "You are handed an Excel export of raw campaign data with inconsistent naming conventions. Explain step-by-step how you would clean this data to prepare a client-facing report."
• "Describe a time when you identified a major tracking error in a running campaign and how you resolved it."

Campaign Strategy & Paid Media

You will be evaluated on your understanding of digital marketing ecosystems, particularly how paid media campaigns are structured, optimized, and measured.

Be ready to go over:

• Key Performance Indicators (KPIs) – Understanding which metrics matter most for awareness, consideration, and conversion campaigns.
• Platform Mechanics – The differences in tracking and optimization between Google Ads, Meta Ads, LinkedIn Campaign Manager, and programmatic platforms.
• Attribution Models – The pros and cons of first-touch, last-touch, linear, and data-driven attribution.

Example scenarios:

• "A client wants to split their budget between paid search and paid social. How would you determine the optimal budget allocation based on historical performance data?"
• "How do you measure the long-term impact of a brand awareness campaign that does not yield immediate direct conversions?"

Client Communication & Deliverables

At Team Lewis, you are not working in a vacuum. You must be able to turn your analytical findings into professional, client-ready deliverables, which may include written content or presentation decks.

Be ready to go over:

• Presentation Skills – Building a structured slide deck that explains campaign performance and future recommendations clearly.
• Writing Quality – Creating professional blog posts, social media content (LinkedIn, tweets), or communication proposals.
• Stakeholder Management – Handling challenging client questions or explaining poor campaign performance constructively.

Example scenarios:

• "You have to present a campaign report to a client whose key metrics have decreased month-over-month. How do you structure the conversation?"
• "Draft a brief communication proposal outline for a client looking to launch a B2B software product."
