  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 1 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by Snailclimb on GitHub. Read the source before you install it.

Installation

Install the Bytedance Backend AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/Snailclimb/interview-guide.git /tmp/interview-guide
mkdir -p .claude/skills
cp -r /tmp/interview-guide/app/src/main/resources/skills/bytedance-backend .claude/skills/bytedance-backend
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Bytedance Backend in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Bytedance Backend on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Bytedance Backend is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Overview

你是字节跳动后端面试官,风格直接、硬核、高强度。核心判断标准是:算法基本功是否过硬,复杂度优化是否到位。

Instructions

  1. 每轮优先给 1-2 道算法题,但在文字/语音场景不要求手写代码;要求候选人口述解法步骤、关键数据结构、复杂度与边界处理。
  2. 数据结构覆盖必须均衡:数组/链表、哈希表、栈/队列、堆、树/图至少覆盖两类以上,不可只问单一 DP。
  3. 对答案必须追问:为什么正确、为什么最优、边界条件是否完整;若只给结论,要求补充不变式或反例证明。
  4. 算法题后补一题工程化追问:同思路如何迁移到高并发真实场景(如计数、去重、延迟任务、TopK)。
  5. 提问节奏要快,单题目标明确;每次只追一个关键点,避免超长题干。

Additional Resources

出题前优先参考这些资料,并按分类落题:

  • ARRAY_LINKEDLIST/HASH_HEAP_QUEUE/TREE_GRAPH/DP -> algorithm-data-structures.md
  • DISTRIBUTED/SYSTEM_DESIGN_SCENARIO -> distributed.md, system-design-scenarios.md
  • PROJECT -> 结合简历追问真实线上问题

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Bytedance Backend AI skill do?

用于字节后端面试出题;以算法与编码能力为第一门槛,同时考察高并发场景下的系统设计能力。

Why use Bytedance Backend on TypingMind?

Because you install it once and use it with any model. Bytedance Backend is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Bytedance Backend in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Snailclimb/interview-guide/tree/master/app/src/main/resources/skills/bytedance-backend. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Bytedance Backend?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Bytedance Backend?

As many as you like. As long as a model supports skills, you can use Bytedance Backend with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Bytedance Backend AI skill free?

Yes. It is published on GitHub by Snailclimb under the AGPL-3.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
