Amazon Operational Strategy & People Analytics Externship

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.

Data AnalysisPythonStrategyOperations

Overview

The externship examined how operational practices and workforce sentiment interact in Amazon fulfillment centers. The work combined web-scraped employee reviews with qualitative and quantitative analysis to surface patterns in early-tenure turnover. Deliverables included extracted insights and persona-driven recommendations based on employee feedback and operational context.

Amazon Operational Strategy & People Analytics Externship

What I've accomplished

I produced a role-by-role spreadsheet that mapped AFC responsibilities, collaborators, and systems, and used it alongside employee-review analysis to surface patterns in early-tenure turnover.

Project breakdown

The project mapped AFC roles and responsibilities, listed who each role worked closely with, and noted common tools and operational notes. The deliverable produced a role-by-role spreadsheet showing responsibilities, collaborators, and systems used.

I reviewed Glassdoor feedback, extracted 6 positive and 6 negative examples, noted recurring themes (management issues, pay/benefits, scheduling), and summarized observations linking specific review text to each theme.

I merged cleaned Glassdoor and YouTube records, added sentiment polarity/subjectivity and labels, and produced side-by-side charts and keyword summaries to compare tone and recurring themes across platforms.

I identified three themes from 32 reviews, tagged each item by theme and sentiment, compiled representative quotes, and produced a summary table showing counts and platform breakdowns, finding most mentions were negative and physical exhaustion was the most frequent issue.
