What it does
The Interview Mentor turns an agent into an interviewer on a chosen topic. Each skill is a separate persona with interview phases (warm-up, core concepts, problem solving, wrap-up), a problem bank with optimal solutions and an evaluation rubric. Difficulty adapts to the answers, and a stuck candidate gets four hint levels from a gentle nudge to a full walkthrough. The catalogue is split by level (SWE-I, SWE-II, Senior+) and role: data engineer, DevOps and SRE, frontend, ML engineer, AI product management, debugging and incident response, behavioural questions. Explanations use ASCII diagrams and Remotion components.
Who it is for. Developers preparing for technical interviews at large companies who want to practise as a dialogue with an agent.
Good fit when
- You want a rehearsal for a system design interview, for example a URL shortener.
- Preparation follows a seven-week plan and each stage needs its own topic.
- Someone is stuck on an algorithm problem and wants a hint without the answer.
- You want to work through behavioural questions and team conflict.
Not a fit when
- You need a real recruiter's verdict: the agent produces the assessment itself.
- You need an interview in a language the problem bank does not cover.
- You want to screen candidates at your company: the set is built for practice.
Example request
Run a system design interview with me on a URL shortener and give hints level by level.Limitations
Assessment and hints come from a model rather than a live interviewer, so check readiness against practice on real problems and feedback from people. The problem bank is limited to what each skill's `references/problems.md` describes, so rare topics and narrow stacks are covered thinly. Candidate answers and code go to your client's model under its privacy rules. The interactive version on socialistic.ai is a third-party service. The plugin installs all 44 skills at once and their list takes space in the agent's context. MIT license.
How to disable. Remove the plugin through `/plugin` in Claude Code or drop the `coding-interview-preparation-agents-marketplace` marketplace.
FAQ
How many interviewers does the plugin have?
Forty-four. They install together and cannot be chosen one by one when installing the plugin.
Does it work outside Claude Code?
Yes. Each skill is a markdown file whose content can be pasted into ChatGPT or Claude.ai.
How do I get new interviewers?
Run `/plugin marketplace update coding-interview-preparation-agents-marketplace`.
Can I add my own skill?
Yes. Copy `templates/skill-template/`, fill in the topic and questions, place it in the right `agents/` directory and open a pull request.
Do I need to sign up for a third-party service?
No. The online version on socialistic.ai is optional and the plugin works directly in Claude Code.
