ClaudeJobOfferHelper

A skill packaged as a plugin for Claude AI that helps with assessing and shortlisting job offers, and with the first contact, the so-called motivation or cover letter. Optimised primarily for IT positions.

Motivation

• Speeding up and automating the process of assessing whether an offered position is a good fit.
• Going through offers and shortlisting them, or ruling out the clearly unsuitable ones, based on several criteria.
• Rating the offer and finding out what is missing, whether on the candidate's side or on the company's.
• • A table summarising any missing requirements with an estimate of how serious they are.
  • A list of the warning signs found (the so-called red flags) with an interpretation of what they mean, along with inconsistencies and missing basic information.
• Help with writing a so-called motivation or cover letter.
• • Also with AI use in ATS systems in mind.

How it works

Requirements

• You need to have the Claude Code CLI installed
• The plugin should work on all three major consumer operating systems (Windows, Linux, macOS)
• The skill is packaged as a Claude Code plugin, so you just install it. The tools it needs are already included, and it shouldn't require installing anything else, apart from having one of the major web browsers.

The shortlisting process and features

Information on using the plugin itself is available in the README (https://github.com/K0V0/ClaudeJobOfferHelper/blob/main/README.md)

Finding out about the candidate, their abilities and preferences

• At the start, the application asks you to provide as much material as possible from which it can work out your professional focus and profile. Give it your CV, LinkedIn profile or personal website with a portfolio, or some other document.
• After that comes clarifying certain work preferences (home office, on-call duty, competences and responsibilities, ...) and which specialisation and seniority you are aiming for.
• The findings are saved to a file with your profile.

Interview

• The agent then starts interviewing you, asking 4 to 10 questions about a given technology, depending on whether it is a core technology for the specialisation (for example a language or framework, like Java or Spring Boot) or a specific technology that doesn't have to be used on every project in the "Java Backend" specialisation (for example MongoDB)
• The questions are not some kind of professional exam or school test, it is always a question of whether you have used a given feature or not (for example: "Have you used threads? Have you used a thread pool?")
• Questions are usually answered by
• • Selecting all the options that are true
  • A yes / no answer
  • Or your own text, a brief clarification
• The findings are saved to a file with your profile
• The interview may briefly come back if, in the next step, you give the application a job offer in which it finds technologies and requirements it has no record of yet and needs to fill in.

Rating how well a job offer or offers fit

• Once the interview is over, you can start giving the agent job offers - either the copied text or a link to a specific offer
• • The best-known Czech and Slovak IT job portals already have a set of scraping scripts built for them, so getting the text of an offer shouldn't burn precious tokens on parsing HTML
  • The interview may start again and ask about newly discovered technologies and requirements
• The agent then tries to take the offer apart and find out:
• • The essential requirements and scope of responsibilities for the position
  • Requirements that are not mandatory but earn extra points
  • The candidate's preferences (home office, pay, scope of responsibilities, seniority, benefits, ...)
  • Red flags - the skill has been taught a database of the most common clichés of corporate newspeak:
  • • Catching red flags and offering the candidate a possible interpretation.
    • Each red flag is rated for severity and type.
    • For each red flag, the candidate gets a tip for an "uncomfortable, direct question" for the recruiter/HR.
  • inconsistencies, missing information and contradictory information
  • • The candidate gets a list of tips on which topics they should raise in their own interest and which "uncomfortable questions" need to be asked and answered at the interview.
• Presenting the results to the candidate
• • Table 1: basic information and an overview of the offer
  • Table 2: score breakdown
  • Table 3: a list of must-have and "nice to have" skills with a verdict on each, and an overall percentage rating per category
  • Table 4: a list of the candidate's requirements
  • Table 5: findings - missing information, inconsistencies, red flags
  • 6: final recommendation

Generating a motivation letter

This is a feature that can never be tuned to perfection, so it should only be used as inspiration, and the answers always need review and human intervention. I strongly recommend that every candidate weighs the style and content of this oddity, a love letter or self-praise addressed to a company, according to the context, which the agent may not judge correctly.

• Before generating, another interview may be run, aimed more at soft skills, ways of working and interaction within the team, strengths and achievements.
• The agent always generates two versions of this letter, one "basic" and one with certain optimisations applied (mainly more frequent use of keywords) for the AI ATS filter.
• Before generating, the candidate also picks the tone the cover letter should take, based on the request that prompts writing it, for example:
• • Tell us something about yourself
  • Tell us why we should choose you
  • How will you be useful to our company?
  • ....

Example

Text of the offer

Hello from Example Company!

You have several years of Java development behind you, you use Spring Boot every day and you want to work on systems that make sense? Then we would love to meet you!

Who we are

We are a software company. We build custom systems and offer development teams to our clients. We use modern technologies and care about the quality, readability and maintainability of code.

Where do you fit in?

Orders keep coming in, so we are looking for someone to strengthen the team. On this project we are helping to develop a new tool for a client in logistics.

What should you bring to make this work?

Your main job will be backend development in Java 17+ and Spring Boot, and you should have at least 3 years of commercial experience. Knowledge of JPA and Hibernate for working efficiently with the data layer and relational mapping. Experience with relational databases such as PostgreSQL or MySQL. Hands-on experience designing and integrating REST and SOAP APIs. Knowledge of Apache Kafka for event-driven architecture and asynchronous communication between microservices. You care about code quality and have experience with automated testing (JUnit, Mockito, possibly Testcontainers). Knowledge of Git for version control and familiarity with CI/CD pipelines for automated build and deployment. The ability to work in a team, learn from colleagues and perhaps teach them something new. English and Czech at a conversational level (daily stand-ups).

What awaits you on the project?

Taking part in a project in the logistics field. Developing and maintaining microservices written in Java 17+ in Spring Boot - from the brief through implementation and testing to deployment and operation. Working in a small team of developers + PO, QA and TL. An agile environment - 2-week sprints including all the ceremonies. Using tools such as Atlassian, Azure cloud, GraphQL, Sonar, Postgres, Kafka, Keycloak, Redis and more. A friendly atmosphere where proactivity is valued.

Why should you join?

## Normal version

Hello,

Your offer caught my attention, mainly because the project is in logistics. I would like to learn more about it.

Briefly about me:

- Java backend: I am in my sixth year as a Java backend developer and that is what I primarily want to focus on.
- Logistics: I used to work at a freight forwarding company, so I have basic know-how in this field.

Where I can add value:

- A feature as a whole: we agree on the approach and I then take it on my own all the way to deployment. That is also how I work on my own projects.
- The business picture: I want to know why a given implementation is needed and who it helps.
- Quality: I don't like doing things twice, so I take care over tests and code readability.
- Working together: remote work and an IČO contract suit me. I live in the Central Bohemian Region, so occasional presence on site is no problem either if needed.

You can find more about me and my projects at https://kovo.space, LinkedIn profile: https://www.linkedin.com/in/kovac-matej/

I would be glad if my profile interested you and we get the chance to discuss the details.

Best regards
