How ChatRex quadrupled recruitment conversion and cut hiring time from two months to two weeks

Introduction

Recruiting is changing. More and more companies are introducing artificial intelligence into the hiring process, and now it is no longer “hype”, but an effective tool that saves resources and significantly speeds up the work of the HR department.
In this case, we tell you how an AI recruiter built on the basis of ChatRex helped an IT company automate selection, speed up hiring from 2 months to 2 weeks, and increase conversion by 4 times.

Problem: HR overload

The company develops software and receives about 1,500 applications per month for open vacancies. Previously, this meant dozens of hours of routine work - manually sorting resumes, answering the same type of questions, scheduling interviews and checking test items. Hiring time is up to two months per developer.

Regular bot vs vs AI

Previously, the company had already tried to automate communication through a simple bot that responded to keywords. But this approach turned out to be ineffective - many candidates were “lost” due to incorrect message processing.

If the candidate's message did not match the expected patterns, the bot simply did not understand how to respond and ended the conversation.
As a result:

• Candidates who wrote freely received incomplete or incorrect answers.
• Even strong specialists could be “lost” if they formulated a request in a non-standard way.
• HR did not have the full picture: some candidates did not reach the funnel, and communication remained opaque.

Solution: switch to ChatRex

With the introduction of ChatRex, the situation has changed. The new AI bot does not just react to phrases, but conducts a full conversation, understands the context and advises candidates. It knows job descriptions, requirements and work scenarios, and all this without the participation of HR

The bot segments candidates:

• Conducts pre-selection based on qualifications
• Sends test tasks
• Accepts answers and checks them
• Schedules an interview

Savings and results

Processing 1,500 responses using ChatRex costs approximately 2,000 rubles. This is several times cheaper than the cost of a recruiter’s work.

In addition:

• Hiring time reduced to 2–3 weeks
• Conversion increased 4 times (compared to a regular bot)
• The HR department is now only involved in the final validation of candidates

Conclusion

AI recruiting is no longer science fiction. This is a real tool that helps you hire faster, cheaper and more accurately

The ChatRex platform allows you to automate the entire process - from response to interview. Especially relevant for businesses with a high incoming flow: IT, education, agencies, B2B.
