Interviewing at Zest AI
What the process looks like, and what Zest AI is really testing for.
You can expect an interview loop that heavily weights technical evaluation, with multiple stages that test coding, analytics, and applied problem solving. The topics data shows Python, Algorithms, Machine Learning, Data Analysis, EDA, Data Wrangling, and Case Study Analysis all rank at or near the top, so your technical preparation should dominate your plan.
The loop is designed to measure how you think under both structured questions and realistic scenarios. You will be tested on Python and data work, the fundamentals of statistics, and machine learning and ML coding, plus case study analysis and whiteboard programming, and scalable architecture design.
The process also includes behavioral and stakeholder fit. Behavioral interviews are reported in the loop, and final stages are described as involving interviews with various stakeholders and potentially the CEO, plus an onsite component that includes both technical and behavioral questions.
Case study analysis and in-person or presentation formats are both explicitly present in the process, including a case study you analyze and present within five days. That means you should be ready to communicate your reasoning, not only solve problems.
