When it comes to preparing for data-related interviews, one size doesn't fit all.
A product data scientist needs to excel in experimentation and metrics design, while a machine learning engineer must go deep into model architectures and system scalability. That’s why we created dedicated interview prep courses, tailored for specific data science roles.
