MP3•Episode home

In this episode we shift gears into the world of data science and machine learning engineering.
Join us as Mykhailo Kuznietsov steps into a real interview setting, answering 30+ questions covering ML theory, data pipelines, prompt engineering, and more.
Hosted by Oleksii Malashyna and interviewed by Denys Soloviov, this session is packed with ML best practices and an engaging live coding challenge — including transforming raw user data into a structured format using Python.
Whether you're preparing for an ML role or just want to learn how top candidates think on the spot, this episode offers deep insights and honest feedback to help you grow!
