⚙️ Technical Questions
1. What are the key features of Python that make it suitable for backend development?
Answer: Python is known for its readability, simplicity, and large standard library. Features like dynamic typing, support for object-oriented programming, and frameworks like Flask/Django make it ideal for backend development.
2. What is the difference between Flask and Django?
Answer: Flask is a lightweight, micro-framework offering flexibility and control, while Django is a full-stack framework with built-in features like authentication, ORM, and admin panel. Flask is better for small apps; Django suits larger projects.
3. Explain REST API.
Answer: REST API (Representational State Transfer) is an architectural style for building APIs using HTTP methods. It allows interaction between client and server using stateless operations like GET, POST, PUT, and DELETE.
4. How would you connect a Python app with a MySQL database?
Answer: Using libraries like mysql-connector-python or SQLAlchemy. For example:
import mysql.connector
conn = mysql.connector.connect(user='user', password='pass', host='localhost', database='test_db')5. What are Docker containers and why are they useful in development?
Answer: Docker containers package an application with its dependencies, making it portable and consistent across environments. This simplifies deployment and scalability.
6. What is the role of Git in software development?
Answer: Git is a version control system that tracks code changes, supports collaboration, and allows rollback to previous states. GitHub or GitLab can be used for remote repositories.
7. How do you ensure security in a backend application?
Answer: Implement input validation, use secure authentication, encrypt sensitive data, apply HTTPS, and regularly update dependencies. Use security headers and avoid hardcoded credentials.
💡 Behavioral Questions
1. Tell me about a project you worked on using Python.
Answer: During my final semester, I developed a library management system using Flask and MySQL. It included user login, book search, and admin controls. I used GitHub for version control and hosted it on a Linux VM.
2. How do you handle debugging and testing in your code?
Answer: I use print statements and Python’s logging module for debugging. For testing, I use unittest and pytest frameworks, and follow test-driven development whenever possible.
3. How do you stay updated with new backend technologies?
Answer: I follow blogs like Real Python, use GitHub trending, and explore new tools on Docker Hub or AWS free tier. I also participate in open-source forums and developer communities.
