Senior Data Scientist Interview Preparation Guide - Weedmaps

Weedmaps's Senior Data Scientist interview process typically consists of 6-7 rounds over 4-8 weeks, evaluating technical depth in Python, SQL, and ML; product thinking and metrics design; business impact mindset; and cultural alignment. At the Senior level, the process emphasizes your ability to own complex analytical and ML projects end-to-end, influence product and business strategy through data-driven insights, mentor junior team members, and thrive in a cross-functional environment. You'll be assessed on your ability to work with large, messy datasets characteristic of a two-sided cannabis marketplace (millions of consumers, hundreds of millions of business interactions), design robust ML systems for production deployment, and communicate complex insights to stakeholders across Product, Engineering, Finance, and Sales.
