April 28, 2026

Updated: April 2026 · By Álvaro Arrescurrenaga, CEO of Voicit

You use ChatGPT to create your candidate reports, and each one comes out different. The structure changes, sometimes data is fabricated, and you end up wasting more time reformatting than if you did it manually. The client receives a document that doesn't look professional—and you know it.

If this sounds familiar, you're not alone. It's the most common problem among recruitment consultancies that are starting to use AI to automate their reports. In this article, I'll explain why this happens, how it can be solved with specialized AI, and how one real consultancy resolved it, reducing the time spent on reports from 45 minutes to less than 15.

Is it possible to write a job interview report in less than 15 minutes?
Yes. With specialized AI that analyzes the interview recording against the job requirements, homogeneous reports are generated and ready to be delivered to the client in a fraction of the time it takes to do it with ChatGPT or manually.

🤖 Why ChatGPT doesn't work for selection reports

If you work at a consulting firm and have tried ChatGPT to generate interview reportsYou've probably come across this:

Each report comes out differently. No matter how much you refine the prompt, the structure, tone, and level of detail change from candidate to candidate. You end up delivering documents to the client that look like they were written by different companies.
Data is fabricated. Misspelled names, skills the candidate never mentioned, conclusions that are not supported by what was said in the interview.
Formatting eats up the time saved. Copying the transcript, pasting it into ChatGPT, reviewing the result, transferring it to a document, adjusting the structure… what was supposed to be automatic ends up costing 45 minutes or more per candidate.
It does not evaluate against the vacancy. ChatGPT doesn't know what skills the position requires. It gives you a generic summary, not a specific one. candidate evaluation against the profile you are looking for.

For a consulting firm that relies on customer trust, delivering inconsistent reports is a serious problem.

🎯 What changes with specialized AI

The difference between ChatGPT and an AI designed for recruitment isn't one of degree, it's one of category. If you want to see the detailed comparison between Voicit and ChatGPTWe have a dedicated article. In short, here's what changes:

You give them the context of the vacancy — job description, required skills, evaluation criteria. AI doesn't work in a vacuum.
Analyze the recorded interview — You don't need to transcribe anything. You record the interview (in person or via video call) and the AI processes it completely.
Evaluate the candidate against the competencies — generates a selection report structured, not a generic summary.
The structure is always the same — It doesn't matter if you do 3 interviews a day or 30 a week. The output is consistent, professional, and ready for the client.

📊 Real case: Hotlist

Hotlist It's a human resources consultancy specializing in the hospitality industry. They've been using Voicit Since January 2026, they have completely transformed their reporting operations. Here's what their CEO says:

Lucía García, CEO of Hotlist, shares her experience with Voicit

Previous: ChatGPT and frustration

Like many consulting firms, Hotlist They started using ChatGPT to create the selection interview reports that they delivered to their clients:

"We used ChatGPT to create candidate reports to give to our clients. It was a disaster. No matter how much I tried to train it to always produce the same result, it gave me something different every time. Sometimes it even made up the candidates' names."
— Lucía GarcíaCEO of Hotlist

The problem wasn't just individual quality, but the image they projected as a company:

"What worried me most as an outsourcing company was that we were giving the client a different result each time. The structure of the report was different from the previous one. We had to invest time in structuring it so that everything was more homogeneous and it seemed like it was done by the same company."
— Lucía GarcíaCEO of Hotlist

Next: professional reports in minutes

When Hotlist started using Voicit, the initial reaction was skepticism:

"At first I was a little hesitant. I thought: ChatGPT doesn't do this anymore. But it's nothing like that. You can tell when something is specialized and trained for it."
— Lucía GarcíaCEO of Hotlist

Now Hotlist configures the job offer, skills, and job description in Voicit. AI analyzes the interview recording and automatically generates a professional selection interview report, evaluating the candidate against the requirements of the vacancy.

"The difference we've noticed, and that our clients have told us about, regarding the professionalism of our reports is incredible. Whereas before creating a report took 45 minutes or an hour, now we can do it in less than 15 minutes. Incredible."
— Lucía GarcíaCEO of Hotlist

Another aspect that Lucía highlights: customer serviceIn a tool that integrates into your daily operations, having the team behind it listen to your feedback and implement it makes all the difference between just another software and a real solution.

👥 Who is AI specialized in selection for?

You don't need a huge volume of interviews for it to be worthwhile. If you deliver candidate reports to clients and want them to be professional, consistent, and quick to produce:

Recruitment consultancies who outsource processes and need standardized reports for each client.
Headhunters and executive search where the quality of the report is part of the service you sell.
Agencies with teams of recruiters that need to standardize the output of the entire team.
Freelance recruiters who want to project a professional image without wasting time on formatting.

"I would recommend it not only to headhunters or freelance talent scouts, but also to agencies with recruiters to streamline their internal operations, evaluate their teams, and ensure that what reaches the client always has the same structure and the same output."
— Lucía GarcíaCEO of Hotlist
