- Work with cloud platforms and automation tools for testing, deployment, and monitoring.
Required Skills
- Strong backend development, data processing, and API development skills.
- Extensive experience with Python frameworks such as FastAPI, Flask, or Django.
- Strong knowledge of relational databases, data modeling, and advanced SQL queries.
- Working understanding of AI/ML concepts, including embeddings, vector search, or retrieval-augmented generation (RAG).
- Experience benchmarking backend systems, databases, or ML model inference.
- Experience developing and deploying cloud applications, preferably in Azure.
- Knowledge of version control using Git and CI/CD deployment pipelines.

Technical questions 5
What is the difference between WHERE and HAVING clauses in SQL? Answer
Model answer: WHERE filters rows before any groupings are applied, while HAVING filters aggregated groups after GROUP BY has executed.
Explain SQL Window functions: ROW_NUMBER(), RANK(), and DENSE_RANK(). Answer
Model answer: ROW_NUMBER() assigns unique sequential integers. RANK() assigns identical ranks to ties and skips ranks. DENSE_RANK() assigns identical ranks to ties without skipping rank numbers.
How do you handle NULL and missing values during data cleaning in Python/Pandas? Answer
Model answer: Use .isna().sum() to identify missing values. Impute with mean/median using .fillna() or remove with .dropna(subset=[...]) depending on variance impact.
What is the difference between Star Schema and Snowflake Schema in Data Warehousing? Answer
Model answer: Star Schema has denormalized dimension tables directly connected to the central Fact table. Snowflake Schema normalizes dimension tables into sub-dimensions to minimize redundancy.
How do you calculate MoM (Month-over-Month) growth in SQL? Answer
Model answer: Use LAG(revenue, 1) OVER (ORDER BY month) to fetch the previous month's revenue and compute (revenue - prev_revenue) / prev_revenue * 100.
