Quick Overview

This question evaluates a candidate's competency in applied machine learning and data science, covering model development and evaluation, data preprocessing, metric design aligned to business objectives, experimental and observational analysis, and creator engagement/product analytics.

You are interviewing for a Data Scientist intern role at a short-video platform. Use a recent data or machine-learning project from your resume as the context.

Answer the following interview prompts:

Project and technical deep dive: Briefly describe the project, the business problem, the data used, and your role. Explain how you performed data preprocessing, how you handled the bias-variance tradeoff, how you selected model or analysis performance metrics, and how those metrics connected to the business objective.
Product launch research case: Suppose the company wants to launch the product or feature you built. How would you design the research plan before and after launch? Include hypotheses, user segments, data requirements, experiment or observational design, success metrics, guardrail metrics, and decision criteria.
Creator engagement case: Assume you have a metric such as the number of new users who registered and published at least one post on the same day. The company wants to improve creator engagement. How would you analyze the problem and recommend next steps?
