3. Interview Process Overview

The interview process at NIKE can vary significantly depending on the specific team (e.g., Supply Chain vs. Consumer Insights) and the role level. However, most candidates experience a structured progression designed to filter for both technical capability and cultural fit. Generally, the process begins with a recruiter screen, followed by a technical assessment, and culminates in a final round of interviews.

In recent cycles, some candidates have encountered an automated digital interview (HireVue) early in the process, consisting of pre-recorded behavioral and situational questions. Others have moved directly to a screening with a Hiring Manager. A critical detail to note is the potential for live technical screenings early in the process. Candidates have reported sessions with Hiring Managers that immediately jump into hands-on SQL and Python coding exercises, sometimes without explicit prior instructions on the interview format.

The final stage typically involves meeting with multiple team members, including peer data scientists, product partners, and leadership. These sessions mix deep technical dives with behavioral questions. The overall pace can be slower than the industry average, so patience is required. The philosophy is thoroughness; they want to ensure you have the technical chops to handle their data scale and the personality to thrive in their collaborative environment.

This timeline illustrates the typical flow from application to offer. Note that the "Technical Screen" phase may involve either an automated assessment or a live coding session with a manager. Use this visual to plan your preparation, ensuring you are technically sharp before the first human interaction, as the difficulty can ramp up quickly.

4. Deep Dive into Evaluation Areas
