Entrevista
It was an hackathon but the invigilator know nothing about data science. They were data analyst and couldnt understand what I am explaining so at the end just asked make graphs on dashboard
I attended one round of panel interview with a data scientist and a data engineer. Overall, the process was pleasant and well-organised. The interview mainly covered ML models, core concepts, and an in-depth discussion of my projects.
