How ChatGPT can help you with candidate searching ?

- Efficient filtering: ChatGPT can assist recruiters in narrowing down the pool of potential candidates by using advanced filtering techniques, especially when combined with a candidate sourcing software. By providing specific criteria such as skills, experience, location, or education, recruiters can generate a list of relevant candidates quickly and effectively.

- Boolean search optimization: ChatGPT can help recruiters optimize their Boolean search strings to enhance candidate searching. By understanding the syntax and logic of Boolean operators, recruiters can create more precise and targeted search queries, resulting in more accurate and relevant candidate results.

- Generating keyword lists: ChatGPT can generate a list of keywords based on specific job roles or industries. By inputting the desired job title or industry, recruiters can obtain a comprehensive list of relevant keywords to use in their search queries, ensuring the inclusion of all potential candidates.

- Stay updated with industry trends: ChatGPT can provide insights into the latest trends, technologies, and skills within specific industries. This knowledge helps recruiters stay informed and tailor their search criteria accordingly, ensuring they attract candidates with the most up-to-date skills and knowledge.

Write Boolean search with ChatGPT

If you are note familiar with boolean searches, or if you want to find ideas to get to new candidates, you can use ChatGPT to help you define the best boolean search for a job title.

In Leonar.app, we integrates ChatGPT to have directly the generation of Boolean Search. This feature is called “Boolean Query Builder”

The idea is to define what type of candidates you are looking for. Example: “I’m looking for a backend engineer. Our stack is Python and SQL. I’d like someone with devops knowledge”.

As Leonar is integrated with ChatGPT4, you can generate the boolean query by clicking on “Generate a boolean query”. The prompt is integrated in Leonar and will be send to ChatGPT4 to build the Boolean Query.

You will get automatically the job title you will need to use in your Linkedin Recruiter search, and the boolean query for the keywords in oder to meet the requirements you have specified.

Get a list of keywords to use in Linkedin Recruiter with ChatGPT ?

The Boolean Query Builder can also help you find a list of alternative keywords to us in Linkedin Recruiter in your search. If you have a list of job titles for a job position, but you need to find more ideas to look for new candidates, you can used the Boolean Query Builder in Leonar.

For instance, if you are looking for Sales or Marketing candidates, you know that there are several job titles that can match your requirements. You can specify the ones you know and click on “Find similar keywords” to get new ideas. As Leonar is integrated with ChatGPT4, you will get a job titles list automatically.

Another example of use case is if you are looking for candidates in specific sectors or industries. You can use the “similar keywords finder” to expand the search. See the example below where I use this feature to find more keywords related to the luxury and cosmetics industries:

Writing candidates outreach messages with ChatGPT

Writing the outreach messages sequences with ChatGPT

ChatGPT can help you save time writing message. If you need proven starting points, browse our collection of LinkedIn outreach message templates. It is also a source of idea to find new templates to reach out to candidates. Using Leonar, you can generate the messages you wish to send to candidates using the AI Generation feature.

Using the data we have on the company you are hiring for, and using the additional context you will give, Leonar will be able to generate messages templates from scratch, in any language.

Writing personalized outreach message to each candidates

What is time consuming for recruiters is to write for each candidates a personalized message. Recruiters and Talent Acquisition Managers usually add personalization to the messages in order to increase the response rate they get from candidates. However, if you reach out to more than 100 candidate a week, you will not be able to do the personalization for each one of them.

Using Leonar combined to ChatGPT can help you send customized messages to each candidats at scale. Leonar integrates ChatGPT4 to automate the generation of personalized messages.

When you define the messaging sequences in Leonar, you can set that you want AI personalization for specific messages. To generate the customized messages, the tool will be using:

• The standard message template you have define for this recruitment campaign
• The additional instructions you have defined for personalization
• The data you have on the candidates (Summary, background, experience, competencies)

After lauching the recruitment campaign sequence, Leonar will generate the personalized message.

Example of a personalized message generated and written with Leonar:

“Hello André,

I hope this message finds you well. I came across your impressive profile and I am reaching out because I believe you could be a perfect fit for a COO position at a startup I am currently working with.

Your diverse skill set, including expertise in Risk Management, Project Management, and Business Intelligence, caught my attention. I also noticed your experience in Supply Chain Management and your proficiency in various programming languages such as HTML, Javascript, and SQL.

Your current role as Co-Founder at Leonar.app and Licorne Society demonstrates your entrepreneurial drive and ability to contribute to the success of startups. Your passion for helping startups and scale-ups recruit top talent is evident in your work at Licorne Society.

I would love to learn more about your experience in team leadership, lean management, and quality management, as well as your multicultural awareness and public speaking abilities. These qualities are highly valued in the startup environment I am working with.

If you are open to exploring new opportunities and discussing further, I would be delighted to connect with you. Please let me know if you would be available for a conversation at your convenience.

Looking forward to hearing from you soon.”

This email was automatically written by Leonar and ChatGPT. It will be also send automatically to the candidate, if you want so. Or if you prefer to validate manually the content, tasks will be created for each candidates and you will have to validate them in the application.

This technology is a prime example of how recruiting automation saves hours of manual work. It can help you write different type of messages through different channels:

• Linkedin message, Inmail or Email
• Request for connection, first message, first email, follow-ups

Writing your job descriptions with ChatGPT

I often use ChatGPT to write job descriptions. What is important is to give context about the type of company and job you are writing. Give as much information as you have.

Prompt: Act as a Sales Manager, write a job description for Business Developer position in a Tech company using these informations [Informations about the role and the company]

Writing candidates and interviews summaries with ChatGPT

After a job interview, the idea is to share the notes recruiters have been taking to the hiring manager or to their client, if they are working for a recruitment. In order to save time and standardise the brief, you can use ChatGPT to summarize your notes.

The Data you need to share with ChatGPT are the following:

• Your notes
• The template you use for candidates brief

In Leonar, you can automatically generate the summary using the AI integration with ChatGPT. On a candidate’s profile, after writing your notes and defining the template you want, you can generate the summary and share it with your clients and/or hiring managers. A prompt is integrated is this feature and you do not have to write it down each time you want to use this feature.

How it works ? Leonar will use the notes and the template and integrate this data into a prompt. In answser, you will get a clean written brief of the interview you had with the candidate.

Leveraging ChatGPT for Recruitment Copywriting: Blogs and LinkedIn Posts

If you are focusing on Inbound Recruitment, AI can be useful to help you write blog article or LinkedIn and empower your employer branding.

Recruiters can harness the power of ChatGPT to elevate their copywriting for blogs, marketing and LinkedIn posts, ensuring their content is both engaging and effective. Here’s how:

Understand Your Audience: Before you begin, clearly define who you are writing for. Are they industry professionals, job seekers, or perhaps your own recruitment team? ChatGPT can assist by generating audience-specific content that resonates and engages.

Crafting Compelling Job Descriptions: Use ChatGPT to transform mundane job listings into captivating narratives. The AI can suggest active, persuasive language that paints a vivid picture of the roles and helps them stand out in a crowded job market.

Creating Consistent Content: Regularly updating your blog and LinkedIn page can be daunting. ChatGPT can help by generating content ideas, outlines, or even full drafts based on the latest industry trends and news, keeping your content calendar full and timely.

Personalizing Outreach: ChatGPT can tailor your communication to different segments of your audience. For LinkedIn posts targeting executives, the tone can be more formal and data-driven, while blog posts for job seekers might be more casual and inspirational.

SEO Optimization: For your blog to be found by the right audience, it needs to be optimized for search engines. ChatGPT can suggest relevant keywords and phrases that improve the visibility of your articles and posts.

Engagement and Interaction: Encourage interaction by using ChatGPT to come up with compelling questions and discussion prompts that invite comments and shares, increasing the reach of your posts.

Analyzing Feedback: After your content is live, use ChatGPT to analyze comments and feedback to understand what your audience resonates with. This insight can guide the creation of future content.

Iterative Improvement: ChatGPT can help you refine your copywriting over time. By analyzing the performance of your past posts, the AI can suggest adjustments in your writing style or content strategy.

Now you have a better vision of how ChatGPT and AI can help talent acquisition teams improve their daily work and reach out to top candidates. The key is to start small: pick one workflow (like Boolean searches or outreach messages), build a habit around it, and then expand to other use cases.
