Imagine shaping how AMAZON — yes, THE Amazon — welcomes and keeps its workforce. Every year, Amazon loses billions because new hires leave before Day 90. You’re going to fix that. In this externship, you’ll web scrape real-world employee reviews from across the web, extract actionable insights, and design persona-driven strategies to help Learning Ambassadors connect smarter, faster, and more humanely. It’s part research, part strategy—and all about learning how people data drives big decisions.
The externship analyzed employee feedback and operational context for Amazon fulfillment centers to surface patterns affecting early-tenure retention. I combined scraped employee reviews with role and process analysis, then synthesized persona-driven findings and recommended interventions. The work produced a set of evidence-backed observations and a persona framework.

I researched fulfillment center operations, analyzed employee review data, and translated those findings into concise observations and personas that reflect early-tenure experiences.
