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.
The recruiter kept messaging if i am available for an interview and never follow through. Reached out me multiple times on different occations to leave ghosted. Felt there is no point in me following up again
