Recruitment

A recruitment platform operating at a scale that manual calling couldn't keep up with

One of India's most widely used recruitment platforms connects tens of millions of job seekers with thousands of employers across nearly every major industry. Built on AI-powered matching and one of the country's largest recruiter networks, the platform had earned its place as a go-to destination for both talent and hiring teams.

But operating at that scale comes with a specific problem. Candidates expect to hear back quickly. Employers expect a pipeline that moves. And the window between someone registering their interest and actually being reachable is shorter than most people realise. The platform's growth had outpaced what its outreach model was built to handle.

The core infrastructure was strong. The matching logic worked. What needed fixing was the first mile of candidate engagement, the moment between a job seeker showing up and a recruiter actually speaking to them.

The Challenge

Two audiences. One bottleneck.

The platform serves two very different groups, and both were being let down by the same slow outreach process. Improving engagement meant solving for both at once.

Audience 01

Job Seekers on the Platform

Millions of registered candidates, some actively hunting, others passively open to the right opportunity. Many had signed up and never heard back. Others had updated their profiles but sat uncontacted for weeks.

Active job seekers looking for immediate placements
Passive candidates open to the right role at the right time
Dormant profiles with updated skills and fresh availability
Re-engagement candidates who'd gone cold after initial registration

Audience 02

Employer Clients

Thousands of businesses using the platform to fill open positions. They weren't just waiting for CVs. They needed qualified, interested, available candidates, fast. Every day a role stayed open had a cost attached to it.

Enterprises with multiple active job openings across departments
Hiring managers expecting pre-screened shortlists, not raw candidate lists
Businesses measuring platform ROI by time-to-hire, not just volume
Clients who'd reduce spend if the pipeline kept moving too slowly

Business Challenge

What was actually breaking

Recruitment is a timing game. A candidate who doesn't hear back within a few hours will often move on to the next platform that contacts them first. An employer waiting days for a screened shortlist starts wondering whether the platform is worth the subscription. The manual telecalling model had worked when volumes were manageable. It was never designed for where the platform now stood.

There's also a ceiling on what a human calling team can do in a day. You can hire more agents, but that costs money and takes time, and even then you're capped by the hours people can work. The platform needed a different kind of engine entirely.

Delayed Candidate Engagement Candidates were being contacted hours or days after registering. By then, many had already moved elsewhere.

Hard Scalability Ceiling More outreach volume meant more headcount. The model couldn't scale without proportionally rising costs.

High Operational Costs The cost per qualified lead kept rising as the team grew to serve a database that was growing faster than the callers could cover.

Recruiter Time Wasted on Cold Calls Recruiters spent the bulk of their day on first-touch cold calls, leaving little time for candidates who were actually ready to move.

Missed Employer Expectations Employer clients were losing patience as hiring timelines extended well beyond what modern businesses could afford to wait through.

Solution

Voice AI integrated directly into the recruitment workflow

Rootle's Voice AI was wired into the platform's existing recruitment process. Not as an add-on sitting to the side. As the first point of contact for every incoming job seeker and a proactive sourcing layer for every active employer opening.

The conversations didn't sound like scripts. Candidates could tell the AI their current situation, update preferences, confirm availability, and express interest in relevant roles. That information went cleanly into the pipeline. By the time a human recruiter got involved, the groundwork was already done.

Automated outreach to registered job seekers Voice AI contacted candidates on the platform's behalf, reaching them at the right moment after registration rather than days later, when interest had already cooled.

Qualification and preference collection Each call gathered current job preferences, employment status, location requirements, and availability, saving recruiters the time they'd normally spend collecting that data manually.

Profile verification and detail confirmation Skills, experience, and candidate preferences were verified during the call. Incomplete profiles stopped being a problem because the AI could fill the gaps in real time.

Recruiter follow-up scheduling Candidates who cleared initial qualification were handed off to recruiters with full context already captured. No more starting from scratch on every call.

Proactive candidate sourcing for employer clients For active openings, Rootle reached out to relevant candidates on behalf of employer clients, accelerating shortlist delivery and reducing time-to-hire across the board.

Implementation

Three workstreams, one unified Voice AI layer

Deployment spanned the full recruitment funnel, from first contact through to recruiter handoff. Each workstream had its own tailored call flow. All of them fed into the same qualification pipeline.

Reaching candidates before anyone else does

Automated outbound calls triggered at the optimal moment post-registration
Collection of updated job preferences, expected roles, and location requirements
Clear identification of actively searching candidates versus those who are passively open
Re-engagement of dormant profiles through personalised, contextual outreach at scale

Qualification that saves recruiter hours every day

First-touch qualification conversations covering role fit, seniority, and readiness
Experience and skill validation completed before any human recruiter gets involved
Availability checks that distinguish between immediate and future-ready candidates
Structured, consistent call flows that produce clean and immediately actionable data

Recruiters focused on closing, not cold-calling

Pre-qualified candidate leads delivered directly into recruiter queues
Significant reduction in the number of manual calls each recruiter handles per day
Faster pipeline movement from first contact all the way through to placement
More recruiter time per day reserved for high-value conversations with genuinely interested candidates

Results

What actually changed

The impact was visible across every part of the funnel. Outreach volume scaled without any proportional increase in team size. Recruiters started the day with qualified leads instead of cold lists. Employer clients got shortlists faster, and candidates heard back while their interest was still warm.

4x Outreach Volume Scaled Thousands of candidates reached simultaneously without adding headcount to the floor.

55% Higher Candidate Engagement Rate More candidates responded and stayed engaged versus the manual calling baseline.

3.2x Faster Time to Qualified Lead From first contact to a recruiter-ready, pre-screened lead in a fraction of the previous time.

40% Recruiter Productivity Gain More placements per recruiter per day because first-touch handling moved fully to the AI.

68% Reduction in Manual Calling Effort Less than a third of the previous calling volume, with consistently cleaner output quality.

2x Faster Employer Shortlist Delivery Employer clients received qualified candidate shortlists at twice the previous speed, consistently.

Manual calling at this volume was never going to hold. We needed something that could reach a candidate the moment they registered and still feel like a real conversation, not an IVR. Rootle delivered on both counts. Our recruiters now start the day with candidates who are already interested, already qualified, and already expecting a call. That one shift changed the entire character of how our team works. We're not chasing leads anymore. We're closing them.
