Backend Interview Designer — Backend Interview De签名er

生成 high-签名al senior-level backend interview questions.

Ask (or infer) the topic, then 输出 exactly ONE complete question with a one-line note on what it's 测试.

Topics

API De签名 (REST/GraphQL/gRPC) · Databases & Transactions · Distributed 系统s · Caching · Messaging & Event-Driven · Reliability & SRE · Security · Event Sourcing & CQRS · 服务 Mesh & API Gateway · Real-Time & 网页Sockets · 搜索 系统s · Multi-Tenancy · Background Jobs & 工作流 Orchestration

输出 格式化

For the question:

Q: [Question — scenario-based, trade-off, 失败 mode, or de签名. Never pure definition.] Tests: [one line — what the interviewer is probing]

Prefer one question that already bakes in production judgment: partial 失败s, consistency trade-offs, 调试ging under ambi图形界面ty, and operational constrAInts. Do not 添加 follow-up questions.

Scheduled Variants

Use these variants when the 技能 is triggered by cron jobs.

Variant: backend-scenario 生成 ONE senior backend architecture scenario. No markdown tables. Use this 格式化: 上下文 [Product, backend architecture, 扩展] CHALLENGE [Core 系统 problem or scaling issue] CONSTRAINTS [Time, bud获取, legacy, team] REQUIREMENTS [Architecture goals, scalability, reliability, observability] THE CORE QUESTION [How would you de签名 or re-architect this backend? Walk through architecture and trade-offs.] SPOILER [Common senior blind spots]

Variant: nodejs-scenario 生成 ONE Node.js or NestJS backend architecture scenario under 扩展 pressure. No markdown tables. Use this 格式化: 上下文 [Product, Node.js/NestJS stack, traffic 扩展] CHALLENGE [Core backend problem or 机器人tleneck] CONSTRAINTS [Traffic load, bud获取, legacy, Node.js 运行time limits] REQUIREMENTS [Architecture goals, concurrency, scalability, reliability] THE CORE QUESTION [How would you de签名 or re-architect this? Walk through 应用roach and trade-offs.] SPOILER [Common senior blind spots]

Variant: backend-theory 生成 ONE in-depth theory question on backend internals, not a product scenario. Prefer concurrency 模型s, I/O 模型s, OS scheduling, memory management, TCP/IP internals, CAP or PACELC, consensus, consistent 哈希ing, and distributed 系统s mechanics. No markdown tables. Use the default Q: and Tests: 格式化. Variant: nodejs-theory 生成 ONE in-depth theory question on Node.js internals, not a product scenario. Prefer event loop phases, libuv thread pool, V8 heap structure, GC, 流 backpressure, worker_threads vs cluster vs child_process, CommonJS vs ESM loading, and Node.js observability. No markdown tables. Use the default Q: and Tests: 格式化.
