wtf is interview-prep?

This is a skill plugin for Claude Code that generates a tailored interview preparation document when you tell it which company and role you are interviewing for. You provide your resume and the job description, and it produces a structured document covering company research, a plain-language breakdown of the job requirements, a custom self-introduction, example answers for common behavioral questions using the STAR format, a list of questions to ask the interviewer, and a gap analysis that flags where your background does not match the job and suggests how to address those gaps. The skill adjusts how much work it does based on how much time you have before the interview. If you are interviewing tomorrow it produces a trimmed version focused on the essentials in roughly three minutes. If you have a week or more it runs a deeper research pass including competitor comparisons and a longer reading list, taking around twelve minutes. You can also ask for just one section, such as a self-introduction or a gap analysis, without running the full process. It is optimized for the Chinese mainland job market and pulls research from sources like Xiaohongshu, Niuke, Maimai, 36kr, and the Chinese App Store region. It can be used for roles in other countries but the depth of company research will be more limited. The target job types are product management, growth and data product roles, product operations, and business strategy or BD positions. The matching analysis between your resume and the job description is designed to cite evidence from your resume before drawing any conclusion. If your background does not cover a requirement, the tool marks it explicitly rather than inventing a match. Installation involves cloning the repository into the Claude Code skills directory. Once there, Claude Code picks it up automatically on the next launch. The skill works on Claude.ai and other tools that support the standard Claude Skill format as well. It requires web search and file read and write tools, which most Claude agent environments include by default.
