Backend Interview Bundle: 7 Workbooks for Node.js and Python

This bundle covers the backend interview in both major ecosystems, from the runtime up through the frameworks and APIs.

Seven workbooks, 822 interview questions. Each question comes with a model answer, the follow-up the interviewer is likely to ask next, and a drill you answer from your own work.

What’s inside

JavaScript backend

🟢 Node.js (100 questions): the event loop, async patterns, streams and buffers, modules, the file system, process and cluster, and performance

🚂 Express (101 questions): routing, middleware, request and response lifecycle, error handling, authentication, validation, and security

Python backend

🐍 Python (115 questions): data types, functions and closures, OOP, iterators and generators, decorators, concurrency, and memory management

🧪 Flask (112 questions): application structure, routing, blueprints, request context, extensions, templating, and testing

⚡ FastAPI (118 questions): path operations, Pydantic models, dependency injection, async endpoints, validation, security, and OpenAPI docs

🎯 Django (148 questions): the ORM, models and migrations, views, middleware, the admin, authentication, signals, and Django REST Framework

APIs

◈ GraphQL (128 questions): schema design, queries and mutations, resolvers, the N+1 problem and DataLoader, subscriptions, caching, and security

How each workbook works

✅ A concept mind map comes first, so you see the whole topic before the questions start

✅ Questions are graded Foundation, Intermediate and Senior

✅ Full model answers, not one-line definitions

✅ Each answer includes the follow-up interviewers actually ask next

✅ Every question has a drill you answer from your own experience

✅ Fillable PDF: type your answers in, or print and write

Who it’s for

Backend and full-stack developers preparing for interviews at junior to senior level. It’s also useful for frontend developers moving into backend or full-stack roles, and for developers switching between Node.js and Python.
