Dataiku Software Engineer interview questions

The process began with a conversation with a recruiter. This interview focused on understanding the company's mission, structure, and the various open roles. I also provided a brief overview of my educational background and professional experience. The second step was a technical interview centered around a coding problem. The final stage was a take-home challenge. The goal was to implement an API that computes the shortest path between two points while avoiding obstacles.
