The Challenge: Unstructured Onboarding Feedback
Most HR teams collect plenty of feedback from new hires: pulse surveys, onboarding questionnaires, emails to HR, messages to managers, and posts in collaboration tools. But this onboarding feedback is scattered across channels, inconsistent in format, and often written in free text. As a result, no one has a single, structured view of how onboarding is performing across cohorts, locations, or roles.
Traditional approaches relied on quarterly survey reports, manual reading of comment fields, or ad-hoc summaries pulled together before a leadership meeting. That might work with a handful of new hires, but it breaks once your organisation scales. HR business partners and people analytics teams simply do not have the capacity to manually code hundreds of comments, compare cohorts, and keep track of changes over time. By the time a report is ready, the data is outdated and the next group of new hires is already experiencing the same problems.
The impact is tangible. Without a structured view of onboarding quality, issues repeat across cohorts: confusing first days, missing logins, unclear expectations, or weak manager involvement. New hires take longer to become productive, early attrition risk rises, and employer brand suffers when people feel their start was chaotic. Leadership decisions about onboarding budgets, content, and tools are based on anecdotes instead of data, which means money is spent where the loudest voices are—not where the real problems are.
This challenge is real, but it is also highly solvable. Modern AI tools like ChatGPT can read large volumes of unstructured onboarding feedback, surface patterns, sentiment, and root causes, and turn them into concrete action items for HR. At Reruption, we’ve seen how fast AI can change the feedback loop when it is implemented with the right strategy and governance. In the next sections, you’ll find practical guidance on how to use ChatGPT to finally make your onboarding feedback as structured, actionable, and fast as your hiring processes.

Our Assessment
A strategic assessment of the challenge and high-level tips how to tackle it.
From Reruption’s hands-on work building AI assistants, recruiting chatbots, and document analysis tools, we’ve learned that the real value of ChatGPT in HR is not just better text—it’s better decisions at higher speed. When you apply that to unstructured onboarding feedback, ChatGPT becomes a powerful layer that turns messy comments into clear insights: themes, sentiment, and prioritized actions that HR and managers can actually use.
Define Clear Questions Before You Touch the Data
The biggest mistake with ChatGPT onboarding feedback analysis is to start by uploading all your comments and asking the model to “tell you what’s going on.” That usually leads to generic themes and little that is decision-ready. Instead, start by defining 3–5 precise questions: for example, “What are the top friction points in week 1?”, “Where do tools and access fail?”, or “How do new hires perceive manager support?”
This framing guides how you prompt ChatGPT, how you segment the feedback, and which summaries are actually useful for HR, line managers, and leadership. It also sets expectations internally: AI is not there to magically replace your judgment, but to give you a sharper, faster view on predefined onboarding questions that matter for productivity and retention.
Treat Feedback Analysis as a Continuous Workflow, Not a One-Off Project
Many HR teams run a large onboarding survey once or twice a year, then manually build a slide deck and move on. With AI-powered feedback analysis, the real value comes from repetition and trend tracking. Strategically, you should think in terms of a continuous process: every new cohort’s feedback automatically flows into a pipeline where ChatGPT categorizes, summarizes and compares against previous groups.
This shift has organisational implications. HR needs to decide who owns the recurring review cadence, which stakeholders receive AI-generated summaries, and how action items are tracked across sprints. When you set up this operating rhythm from day one, AI becomes part of how you run onboarding, not just an experiment that produces one impressive report and then disappears.
Balance Automation with Human Judgment and Context
AI for onboarding feedback can reliably cluster comments, tag sentiment, and highlight patterns, but it cannot fully understand your culture, unwritten norms, or political constraints. Strategically, design your process so that ChatGPT does the heavy lifting—initial coding, clustering, draft summaries—while HR and people leaders apply context and make prioritization calls.
This means building explicit review steps into your workflow: for example, HR reviews AI-generated themes before they go to the executive team, and local HRBPs sanity-check cohort-specific insights. The mindset shift is to see ChatGPT as an analyst, not as the decision-maker. That protects against overreliance on AI and ensures that changes to onboarding journeys stay aligned with your strategy and culture.
Prepare Your Data and Governance Before Scaling Up
To use ChatGPT in HR at scale, you need more than prompts—you need basic data and governance foundations. Strategically, define which data sources you will include (survey tools, HRIS notes, email exports, chat logs), how they will be anonymized or pseudonymized, and which access controls apply. Decide early which attributes you want to segment by: department, location, seniority, contract type, or manager.
Clear governance also reduces internal resistance. When works councils, IT, and Legal understand that data is anonymized, processed securely, and used to improve onboarding rather than evaluate individuals, you get faster approvals and higher adoption. This is where Reruption’s work on security, compliance, and AI architecture helps teams move from ad-hoc experiments to robust, compliant solutions.
Align Stakeholders Around Measurable Outcomes
Launching ChatGPT on your onboarding feedback without a shared definition of success can create noise: interesting insights, but no change. Strategically, align HR leadership, Talent Acquisition, and key business units on a small set of measurable outcomes: reduced time-to-productivity, higher onboarding NPS, improved first-year retention, or fewer access-related tickets in the first 30 days.
Once these outcomes are agreed, you can design your AI workflows to produce exactly the insights needed to move those metrics. For example, if your goal is to reduce time-to-productivity, you might focus ChatGPT analysis on comments about tools, training content, and role clarity, and then track how improvements shift sentiment over 2–3 cohorts. This makes the ROI of your ChatGPT onboarding feedback solution visible and defensible.
Used deliberately, ChatGPT transforms unstructured onboarding feedback from a messy archive into a real-time radar for HR: clear themes, quantified sentiment, and prioritized actions that directly influence time-to-productivity and new-hire experience. The key is to combine strategic framing, governance, and continuous workflows so AI is embedded into how you run onboarding—not just how you run surveys.
Reruption specialises in building exactly these AI-backed feedback loops: from defining the right questions and prompts to engineering secure, compliant workflows that plug into your existing HR stack.

Best Practices
Successful implementations follow proven patterns. Have a look at our tactical advice to get started.
Centralize All Onboarding Feedback Before Sending It to ChatGPT
The first tactical step is to bring your scattered data together. Export open-text responses from your survey tools (e.g. onboarding NPS, first-90-days surveys), pull anonymized snippets from HR shared mailboxes, and extract relevant feedback from collaboration tools (e.g. onboarding channels in Teams or Slack). Store these in a structured format such as a CSV or simple database with consistent columns like source, date, cohort, department, and comment.
Once centralised, you can feed this dataset to ChatGPT in manageable batches. If you use the ChatGPT API or a custom interface, automate these exports on a weekly or monthly basis so that your onboarding feedback analysis is always up to date. Clear structure going in leads to much better structure coming out.
Use Standardized Prompt Templates for Thematic Analysis
Instead of manually crafting a new prompt every time, define a standard prompt template for onboarding analysis and reuse it for each cohort. This ensures consistency across time and between HR team members, and it makes it easier to compare results.
A practical example for analysing comments from one cohort:
You are an HR analytics assistant helping improve employee onboarding.
Task:
1. Read the onboarding feedback comments below.
2. Identify 5–8 key themes (e.g. tools & access, role clarity, culture, manager support).
3. For each theme, provide:
- Short description
- Example quotes
- Estimated sentiment distribution (positive / neutral / negative in %)
4. List the top 5 concrete, actionable improvements HR and managers should consider.
Context:
- Audience: HR leadership and business unit leaders
- Timeframe: first 90 days of onboarding
- Goal: reduce time-to-productivity and improve new-hire experience
Feedback comments:
[PASTE COMMENTS HERE]Save this as a standard operating prompt. Over time, you can refine the structure (e.g. add severity scores or impact estimates) without reinventing the wheel each time.
Segment Feedback to Uncover Hidden Patterns
One of the easiest wins with ChatGPT onboarding analysis is segmentation. Run separate analyses for different groups—e.g. sales vs. engineering, headquarters vs. plants, junior vs. senior roles. This often surfaces issues that disappear in aggregate data, such as a specific department struggling with access to systems or a location experiencing recurring equipment delays.
To do this, you can filter your feedback data before sending it to ChatGPT and clearly specify the segment in the prompt:
You are analysing onboarding feedback only for:
- Department: Sales
- Location: Berlin
Follow the same steps as the standard onboarding feedback analysis prompt, but highlight any issues that seem specific to this segment and might not affect other parts of the organisation.Use these segment-specific outputs to brief local HRBPs and managers, turning generic survey results into targeted action plans.
Turn Raw Feedback into Ready-to-Use Summaries and Action Plans
Beyond identifying themes, you can instruct ChatGPT to generate outputs that are directly usable in your HR communications: executive summaries, slide content, FAQ drafts, and checklists for managers. This shortens the distance between insight and action.
For example, after you have your themes, ask ChatGPT to create stakeholder-ready artefacts:
Based on the analysis above, create:
1. A 1-page executive summary for CHRO and CEO (max. 300 words).
2. Three slides in bullet form outlining:
- Key themes & sentiment
- Top risks for new-hire experience
- Recommended changes for the next onboarding cohort
3. A checklist for line managers: "First 2 weeks with a new hire" based on the most frequent issues mentioned.This practice ensures your AI-generated onboarding insights lead to tangible improvements instead of remaining as long narrative reports.
Build an Onboarding FAQ Assistant from Real Feedback
You can also reuse onboarding feedback to proactively support future cohorts. Feed typical questions and pain points into ChatGPT and let it draft or refine an internal onboarding FAQ or even power an internal Q&A assistant for new hires.
Start by asking ChatGPT to extract the most common questions embedded in feedback comments:
You are an HR onboarding assistant.
From the following feedback comments, extract:
1. The 20 most common questions or uncertainties new hires had.
2. Group them into categories (IT access, HR policies, benefits, tools, ways of working, etc.).
3. Propose a clear, concise answer for each question in a tone suitable for new hires.
Feedback comments:
[PASTE COMMENTS HERE]Once reviewed by HR for accuracy and policy compliance, these Q&As can be integrated into your intranet, knowledge base, or a chatbot interface so new hires get instant, consistent answers based on real-world needs.
Track Changes Over Time with Structured Output Formats
To measure the impact of your actions, you need comparable data across cohorts. Ask ChatGPT to output its analysis in a structured format—e.g. a table with themes, sentiment scores, and severity ratings—so that you can track trends in Excel, BI tools, or your people analytics stack.
An example prompt for structured output:
Analyse the following onboarding feedback comments and output results as a table with the following columns:
Theme | Description | Positive_% | Neutral_% | Negative_% | Severity_1-5 | Top_3_Recommended_Actions
Only output the table, no additional text.
Feedback comments:
[PASTE COMMENTS HERE]By running this prompt for each cohort and storing the results, you can visualise how particular themes evolve, whether specific interventions are working, and where new issues emerge. This turns your ChatGPT onboarding feedback pipeline into a measurable improvement engine.
Implemented together, these practices typically lead to faster insight cycles (from weeks to days), more targeted onboarding improvements, and clearer prioritisation for HR and managers. Many organisations see onboarding issue detection speed improve by 50% or more and report noticeably higher new-hire satisfaction within 2–3 cohorts, without adding more manual reporting work to the HR team.

Frequently Asked Questions
ChatGPT can read large volumes of free-text onboarding feedback from surveys, emails and chat logs and turn them into structured insights. It clusters comments into themes (e.g. IT access, manager support, role clarity), assigns sentiment, extracts example quotes, and proposes concrete actions.
Instead of HR manually reading hundreds of comments, ChatGPT can generate an initial analysis in minutes. HR then reviews, adjusts and decides which changes to implement. The result is a much faster and more systematic feedback loop without hiring additional analysts.
You do not need a full data science team to start. At minimum, you need:
- An HR or people analytics owner who understands your onboarding process and key questions.
- Basic data handling skills to export survey responses and collate comments into CSV or text files.
- Access to ChatGPT (web or API) and clear internal guidelines for handling employee data.
Over time, you can involve IT or your HRIS team to automate data exports and integrate AI outputs into your existing dashboards. Reruption often helps clients design this pipeline so HR can focus on interpretation and action instead of wrestling with tools.
For most organisations, the first tangible results come within a few weeks. Once you have exported existing onboarding feedback, you can run initial analyses in ChatGPT within days and present a first set of themes and action items to stakeholders.
Visible impact on onboarding quality—such as reduced recurring issues or improved new-hire satisfaction scores—typically appears over 2–3 onboarding cohorts, as you implement changes and then measure feedback again. The key is to run this as a continuous cycle, not a one-time report.
The software cost for ChatGPT-based analysis is usually low compared to HR time: model usage and tooling are typically a fraction of the cost of manual analysis or external survey consultants. The main investment is in initial setup—defining workflows, prompts, data pipelines, and governance.
ROI comes from several areas: reduced time spent on manual comment coding and report creation; faster detection and resolution of onboarding issues; improved time-to-productivity for new hires; and lower early attrition risk. Even small improvements—such as preventing a few early departures or cutting a week from ramp-up time in revenue roles—often cover the investment many times over.
Reruption supports organisations end-to-end, from idea to working solution. With our AI PoC offering (9,900€), we can validate in a few weeks how well ChatGPT can analyse your real onboarding feedback, which data pipelines are needed, and what performance you can expect in your environment.
Beyond the PoC, our Co-Preneur approach means we embed with your HR, IT, and people analytics teams to design secure workflows, engineer the integrations with your survey tools and HR systems, and co-create prompts, dashboards, and playbooks. We operate inside your P&L, not just in slide decks, until a robust, AI-first onboarding feedback process is live and delivering measurable improvements.
