4. Interview Process Overview

The interview process at dentsu is generally structured to move from high-level screening to deep-dive technical and behavioral assessment. While regional variations exist, you should expect a consistent focus on your ability to handle data, manage stakeholders, and fit into a collaborative, agency-style environment. Candidates often encounter a mix of automated assessments—including aptitude and psychometric tests—followed by rounds of virtual or in-person interviews.

This timeline illustrates the progression from initial screening to final managerial discussions. You should interpret this as a multi-stage filter where each round assesses a different dimension of your candidacy: foundational logic, technical capability, and cultural alignment. Ensure you are prepared to sustain your performance across several weeks, as the process can take between 20 to 30 days.

5. Deep Dive into Evaluation Areas

Data Manipulation & Technical Proficiency

This area ensures you can handle the raw materials of the job. You will be evaluated on your speed, accuracy, and depth of knowledge regarding data tools.

Be ready to go over:

• SQL joins, aggregations, and subqueries.
• Excel functions (VLOOKUP, Pivot Tables, Index/Match).
• Data Visualization best practices in tools like Power BI.

Example questions or scenarios:

• "Walk me through how you would join these three tables to find the top 5 performing campaigns."
• "What steps do you take to clean a dataset before importing it into a visualization tool?"

Business Context & Strategic Thinking

Understanding the "why" behind the data is what separates a good analyst from a great one. You are expected to show interest in the marketing landscape.

Be ready to go over:

• Current trends in performance marketing.
• The lifecycle of a marketing campaign.
• How to translate business goals (e.g., brand awareness vs. lead generation) into data metrics.

Example questions or scenarios:

6. Key Responsibilities

As a Business Analyst, your primary responsibility is to transform data into a narrative that helps clients make informed decisions. You will spend your day querying databases, creating automated reports, and maintaining dashboards that track campaign performance.

You will work closely with account managers and media planners to ensure that the data you provide is relevant to the client's current business objectives. Often, this involves participating in client calls or internal strategy sessions where you represent the "data voice" of the team. You are also responsible for identifying anomalies in data and proactively communicating risks or opportunities to your project leads.
