    Back-End Developer Interview Questions

    Back-End Developer Interview Questions

    A list of back-end related questions

    Back-End Developer Interview Questions is a curated collection of discussion prompts for evaluating and learning about back-end software engineering.

Topics cover design patterns, code design, programming languages, algorithms, software architecture, microservices, security, and general engineering concepts. It also includes questions based on code snippets and unconventional problem-solving scenarios. Interviewers can select only the sections relevant to a particular role instead of following the entire list. Developers can also use the repository for self-assessment, study, and identifying gaps in their technical knowledge.

    Karpathy Skills

    Karpathy Skills

    A single CLAUDE.md file to improve Claude Code behavior

    Karpathy Skills is a compact guidance project built around a single CLAUDE.md file for improving AI coding agent behavior.

    Claude Agent SDK

    Claude Agent SDK

    Programmatically build AI agents with Claude Code's capabilities

    Claude Agent SDK (TypeScript) is an official TypeScript/JavaScript software development kit from Anthropic that makes it easier to build AI agents using the same agent architecture that powers Claude Code and other Claude-based autonomous systems. It provides abstractions and tools that let developers programmatically create, configure, and run intelligent agents that can read files, run commands, edit source code, manage sessions, and execute workflows without having to implement the agent loop manually — the SDK handles much of the complexity for you. ...

    Tabris.js

    Tabris.js

    Create native mobile apps in JavaScript or TypeScript

    Tabris.js is a framework for developing mobile apps with native UIs in JavaScript. iOS and Android apps can be built entirely from one code base, which frees you from the task of managing code for multiple platforms. The code of the application is loaded dynamically - nothing is precompiled. JavaScript is executed Just-in-Time and passed via a native bridge to the device. Tabris.js accesses native controls and does not depend on web views to render the app's UI. As a result, the performance of the apps cannot be distinguished from apps developed directly in native code of the platforms. ...

    AutoMapper

    AutoMapper

    A convention-based object-object mapper in .NET

    A convention-based object-object mapper. 100% organic and gluten-free. Takes out all of the fuss of mapping one object to another. AutoMapper is a simple little library built to solve a deceptively complex problem, getting rid of code that mapped one object to another. This type of code is rather dreary and boring to write, so why not invent a tool to do it for us? First, install NuGet. Then, install AutoMapper from the package manager console. AutoMapper is an object-object mapper. Object-object mapping works by transforming an input object of one type into an output object of a different type. ...

    HumanEval

    HumanEval

    Code for the paper "Evaluating Large Language Models Trained on Code"

    human-eval is a benchmark dataset and evaluation framework created by OpenAI for measuring the ability of language models to generate correct code. It consists of hand-written programming problems with unit tests, designed to assess functional correctness rather than superficial metrics like text similarity. Each task includes a natural language prompt and a function signature, requiring the model to generate an implementation that passes all provided tests. The benchmark has become a standard for evaluating code generation models, including those in the Codex and GPT families. ...

    SDL

    SDL

    Simple DirectMedia Layer

    SDL (Simple DirectMedia Layer) is a cross-platform multimedia development library designed to provide low-level access to hardware components such as graphics, audio, input devices, and system resources, making it a foundational tool for building games, emulators, and interactive applications. It abstracts platform-specific functionality into a consistent API, allowing developers to write code once and deploy it across multiple operating systems including Windows, macOS, Linux, iOS, and Android. SDL is written in C but is compatible with C++ and has bindings for multiple other programming languages, making it highly flexible for different development environments. The library is not a game engine itself, but rather a hardware abstraction layer that enables developers to build engines or applications on top of it with full control over performance and rendering. ...
