What is hire?

This repository is essentially a take-home coding challenge for anyone who wants to apply for a front-end engineering position at LeetCode China. Rather than submitting a traditional resume and hoping for a conversation, candidates can complete one or more of the technical tasks listed here and email their code directly to the hiring team. Doing well on these challenges can let you skip the first round of interviews entirely, and higher-quality submissions give you a leg up in later rounds. The project lays out several specific challenges that test skills LeetCode's front-end team uses day to day. These include writing advanced TypeScript types, building predictable long-term caching with Webpack, creating well-engineered reusable components, and handling complex asynchronous business logic with RxJS. The repo also references a foundations file for basic programming ability. A candidate picks whichever challenges play to their strengths, completes them, and sends the code over. The ideal user is a front-end developer who is comfortable with technologies like React, Redux, GraphQL, and TypeScript, and who is specifically interested in joining the LeetCode China team. The work there involves maintaining the main LeetCode site and building enterprise-facing services, so the challenges are designed to mirror the real problems that team solves. It's a practical filter: if you can do these tasks, you can likely do the job. The US team section is marked as a work in progress, so for now the challenges are aimed squarely at candidates for the China team. The README doesn't go into detail on evaluation criteria or timelines beyond noting that submitting code can earn you an interview.
