A repair:
- Follow advanced SQL ideas: subqueries, CTEs, window features, time sequence joins, pivoting, and recursive queries.
- Use platforms like StrataScratch and LeetCode to follow real-world SQL interview questions.
4. Ignoring Product Considering

- Perceive the three essential methods of information processing: batch, real-time, and hybrid processing.
- Perceive machine studying pipelines, CI/CD, and machine studying mannequin monitoring.
- Follow workflow design in your initiatives by together with information ingestion, mannequin coaching, versioning, and serving.
- Get acquainted with machine studying orchestration instruments, corresponding to Prefect and Airflow (for orchestration), Kubeflow and ZenML (for pipeline abstraction), and MLflow and Weights & Biases (for monitoring).
