Data Scientist interview prep
For Data Scientist roles (ML / DS), Indian panels usually test model choice with business impact. Packages for solid profiles often sit around 8–22 LPA, so competition is real — preparation compounds.
What to practise
- Core skills: Python, ML, statistics, SQL, scikit-learn, experimentation
- Prompts to rehearse: Explain a model to a PM; overfitting; feature leakage; offline vs online metrics
- Keep your resume interview-ready — Data Scientist ATS guide
