🧠 SQL Interview Question (Commonly Asked)
📌

products(product_id, product_name, category_id, price)

❓ Ques :

👉 Find the second highest priced product in each category.

🧩 How Interviewers Expect You to Think

• Partition data by category
• Rank products based on price (descending)
• Understand difference between RANK, DENSE_RANK, and ROW_NUMBER
• Handle ties properly
• Filter after ranking logic

💡 SQL Solution

WITH ranked_products AS (
SELECT
product_id,
product_name,
category_id,
price,
DENSE_RANK() OVER (
PARTITION BY category_id
ORDER BY price DESC
) AS price_rank
FROM products
)

SELECT
product_id,
product_name,
category_id,
price
FROM ranked_products
WHERE price_rank = 2;

🔥 Why this question is powerful:

• Tests window functions deeply
• Checks ranking logic understanding
• Very common in Data Analyst interviews

❤️ React if you want more scenario-based SQL questions

Cheat sheet on Python Frameworks:

Django: A full-featured web framework with built-in ORM, admin panel, and security features.

Flask: A lightweight microframework with a minimal set of features and high flexibility.

ORM & Admin: Built-in to Django, but need to be connected separately in Flask.

Security: Django has built-in security mechanisms, while in Flask, they need to be configured manually.

Testing: Django offers built-in testing tools, while Flask relies on third-party libraries.

Use Cases: Django is suitable for large and complex projects, while Flask is better for small applications, APIs, and prototypes.
