2,459 participants. 10,000 survey responses. One real-world marketing problem.
I’m thrilled to share that I placed 2nd in the Codebasics Resume Project Challenge #9, a global competition that tested participants on their ability to turn messy survey data into actionable marketing insights.

This challenge wasn’t just a technical exercise, it mirrored the real-world problems many businesses face:

• How do you understand your market?

• Where are your opportunities?

• What marketing strategies will drive growth?

Let me walk you through how I approached the problem and how these same strategies can help your business win in the marketplace.

The Challenge: Making Sense of 10,000 Survey Responses

The fictional company CodeX, a German beverage brand, had just launched its energy drink in 10 Indian cities. They wanted to understand:

• Who their consumers were

• What marketing channels worked

• How to position their product against competitors

My role? To step into the shoes of their Marketing Data Analyst, Peter Pandey, and deliver a 15-minute, CMO-level presentation of marketing insights and strategic recommendations.

Tools & Methods I Used

To analyze the survey data, I leveraged:

• Python (pandas, seaborn, matplotlib) for data cleaning and exploration

• Statistical techniques like the Chi-Squared test for identifying brand perception drivers

• Marketing theory to frame insights in a business-relevant way

• Storytelling and visual design to deliver an engaging executive presentation

This was more than just analysis—it was insight transformation.

The Insight Journey: From Data to Strategy

The presentation was divided into two phases:

✅ Phase 1: Deep Dive Analysis

• Defined the target market using demographics and preferences

• Mapped brand awareness and channel effectiveness

• Identified purchase behaviors and brand penetration gaps

• Benchmarked CodeX against its competitors

✅ Phase 2: Strategic Marketing Plan

• Created customer personas

• Applied the 4P’s of Marketing (Product, Price, Place, Promotion)

• Developed a mock advertising campaign

• Suggested actionable strategies for product development and channel optimization

The final presentation simulated a pitch to the CMO—sharp, focused, and data-driven.
