Why Most Recruiters Get Rubbish Results from AI

Every recruiter has tried ChatGPT at least once by now. Most typed in something like "write me a job advert for a software developer" and got back something so generic it could have been written by a first-year HR student in 2015.

The problem is not the tool. The problem is the prompt.

AI is only as good as the instructions you give it. A vague prompt gets a vague result. A specific, well-structured prompt gets something you can actually use. The difference between a recruiter who thinks AI is "a bit rubbish" and one who saves five hours a week usually comes down to knowing how to write better prompts.

Here are seven of the most useful prompts for recruiters in 2026. These are not theoretical. They are tested, refined, and used by working recruiters in the UK right now.

Prompt 1: The Job Advert Writer

Most job adverts fail because they describe the role instead of selling it. This prompt fixes that.

The prompt:

You are an expert recruitment copywriter. Write a job advert for the following role that will attract top-tier candidates on LinkedIn and job boards.

Role: [Job Title]
Company: [Company Name, brief description]
Location: [Location, remote/hybrid/office]
Salary: [Range]
Key responsibilities: [List 4-6 main duties]
Must-have requirements: [List essentials]
Nice-to-haves: [List desirables]
Company selling points: [Culture, benefits, growth, tech stack, etc.]

Write the advert in a conversational, engaging tone. Lead with what makes this role exciting, not with a company history paragraph. Keep it under 500 words. Use short paragraphs and bullet points. End with a clear call to action.

Why it works: It gives the AI a clear role (recruitment copywriter), specific inputs, tone guidance, format constraints, and a structure to follow. The output is almost always usable with minor edits.

Prompt 2: The Boolean Search Builder

Building Boolean strings is one of those tasks that takes longer than it should. This prompt handles it in seconds.

The prompt:

Generate a Boolean search string for LinkedIn Recruiter to find candidates matching this brief:

Role: [Job Title]
Location: [City/Region, UK]
Required skills: [List key skills]
Required experience: [Years and type]
Industry preference: [Sectors to include]
Exclusions: [Companies, roles, or sectors to exclude]

Provide three versions: one broad (maximum results), one balanced, and one narrow (highest relevance). Format each as a single copy-paste string.

Why it works: Getting three versions at different levels of specificity means you can start narrow and widen your search if needed. Most recruiters find the balanced version works best as a starting point. For a deeper dive into Boolean search strategies, see our guide on using AI as a Boolean search generator.

Prompt 3: The Personalised Outreach Message

Cold InMails have an average response rate of about 10-15% when done well. Generic ones sit closer to 3%. This prompt helps you write outreach that feels personal without spending five minutes per message.

The prompt:

Write a LinkedIn InMail to approach a passive candidate for the following role. Make it feel personal, not templated.

Candidate's name: [Name]
Their current role: [Current Title at Current Company]
Something notable about their profile: [A specific project, skill, or career move]
Role you are recruiting for: [Title, Company, key selling point]
Why they might be interested: [Career progression, tech stack, culture, salary uplift]

Keep it under 150 words. Open with something specific to them, not "I came across your profile." Do not use exclamation marks. End with a soft question, not a hard sell. Tone: professional but warm, like a message from a knowledgeable colleague.

Why it works: The specificity forces the AI to write something that genuinely relates to the candidate, and the constraints on length and tone prevent the usual AI waffle. For more on writing effective outreach, read our full guide on LinkedIn InMails that actually get replies.

Prompt 4: The CV Screener

When you have 40 CVs to review against a brief, this prompt helps you prioritise quickly.

The prompt:

I am a recruiter screening candidates for the following role. Review this CV against the brief and give me a structured assessment.

Role brief: [Paste the key requirements]

CV: [Paste the CV text]

Provide:
1. Match score out of 10 with brief justification
2. Key strengths relevant to this role (bullet points)
3. Potential concerns or gaps (bullet points)
4. Three tailored interview questions for this specific candidate
5. One-line summary recommendation (progress / hold / reject)

Why it works: It gives you a consistent framework for evaluating every candidate, highlights things you might miss when scanning quickly, and generates interview questions you would otherwise have to write yourself. If you are using this with real CVs, make sure to anonymise candidate data first for GDPR compliance.

Prompt 5: The Market Mapping Brief

Clients love market maps, but they take ages to put together. AI can do the heavy lifting.

The prompt:

Create a market mapping brief for the following search. I need to identify target companies and potential candidate pools.

Role: [Job Title]
Sector: [Industry]
Location: [Region/City, UK]
Company size preference: [SME/Mid-market/Enterprise]
Competitor companies to the client: [List known competitors]

Provide:
1. A list of 15-20 target companies where this type of candidate is likely to work, grouped by tier (direct competitors, adjacent companies, emerging players)
2. Alternative job titles this person might currently hold
3. Key industry events or communities where these professionals gather
4. Suggested search strategy (which platforms to prioritise and why)

Why it works: Even if the AI misses some niche companies, it gives you a solid starting framework in minutes rather than hours. You add your market knowledge on top.

Prompt 6: The Client Update Email

Nobody loves writing client update emails. This prompt makes them painless.

The prompt:

Write a professional client update email for a retained recruitment search. Keep it concise and factual.

Client contact: [Name]
Role: [Job Title]
Search stage: [e.g., Week 2 of search]
Candidates sourced so far: [Number]
Candidates at shortlist stage: [Number]
Key findings or market observations: [Brief notes]
Next steps: [What you plan to do next]
Any blockers or concerns: [If applicable]

Tone: professional, reassuring, proactive. Keep it under 200 words. Sign off with a suggestion for a brief call if they want to discuss.

Why it works: Client communication is one of those tasks that falls down the priority list when you are busy. This prompt means a professional update takes two minutes instead of fifteen.

Prompt 7: The Interview Prep Pack

Help your candidates prepare properly and your placement rate goes up. Simple as that.

The prompt:

Create an interview preparation pack for a candidate attending an interview for the following role.

Role: [Job Title] at [Company]
Interview format: [Phone/Video/In-person, number of stages]
Interviewers: [Names and titles if known]
Key areas they will likely assess: [Technical skills, cultural fit, leadership, etc.]
Company background: [Brief overview or values]

Include:
1. Five likely interview questions with guidance on how to answer each one
2. Three questions the candidate should ask the interviewer
3. Key talking points that align their experience with this role
4. Common mistakes to avoid in this type of interview
5. Practical tips (dress code, arrival time, follow-up advice)

Why it works: Candidates who are well-prepared perform better. Better performance means more offers. More offers mean more fees.
