About the Customer
Sybrid is a large contact center and BPO provider, delivering customer support and sales services across multiple client campaigns. Continuous, high-volume hiring of customer support representatives and sales agents sits at the core of its operations, and communication quality, language proficiency, and reliability aren't optional; they're the baseline for every hire.
Training batch schedules and campaign ramp-ups don't wait. Sybrid has to screen and evaluate large numbers of candidates quickly while holding its hiring bar steady across every cycle.
The Challenge
Our recruiters were overwhelmed with hundreds of manual screening calls every week. It was hard to maintain consistency in evaluating language skills, and we often struggled to move candidates quickly into training.
The problem didn't announce itself all at once. It built gradually, call by call, week by week, until the screening stage had quietly become Sybrid's biggest operational drag.
Recruiters were spending the bulk of their working hours on repetitive manual screening, cycling through the same questions for the same types of roles. The throughput ceiling was low, and during peak hiring periods, scheduling alone consumed time that should have gone to evaluation and decision-making.
Quality consistency was the other half of the problem. Language proficiency, grammar, vocabulary, sentence structure, response coherence was being judged differently by different interviewers. There was no shared standard, which made it nearly impossible to compare candidates fairly or move the right people forward with confidence.
What Sybrid was dealing with, specifically:
- 1Recruiter workload from repetitive, high-volume screening calls.
- 2Capacity ceilings that made peak periods especially painful.
- 3Interviewer-to-interviewer variation in how communication skills were scored.
- 4Scheduling overhead that slowed candidate progression into training pipelines.
The volume wasn't going to shrink. Sybrid needed its screening process to scale without requiring more recruiters and to produce evaluations that meant the same thing regardless of who ran them.
The Solution
Sybrid brought in InterWiz to take over manual screening interviews for contact center roles, not as a supplement to the existing process, but as a direct replacement for the early-stage calls that were consuming recruiter time.
The deployment was scoped deliberately: InterWiz at screening, humans at final decision. That boundary meant recruiters and hiring managers stayed in control of outcomes while the operational weight lifted. The platform introduced:
- AI-led screening interviews completed asynchronously by candidates, with no recruiter scheduling required.
- Automated language proficiency assessment covering grammar, vocabulary, sentence structure, and response coherence.
- A consistent interview flow so that every candidate faced the same questions, evaluated against the same criteria.
- Structured reports with recordings, transcripts, scores, and clear shortlisting recommendations.

The result was a screening function that could run continuously, at whatever volume the business needed, without burning recruiter hours.
The Result
Replacing manual screening calls with structured AI interviews cut Sybrid's recruiter workload at the screening stage by 50%. What had been the team's biggest operational drag became essentially self-running.

Beyond the workload reduction:
- Hundreds of interviews completed per cycle, even during peak hiring, without adding headcount.
- Consistent, objective language proficiency evaluation across every candidate.
- Faster movement from screening into training, with cleaner early-stage signals guiding decisions.
Recruiters didn't disappear from the process. They just stopped being the bottleneck. Their time moved downstream, toward decisions that actually require human judgment.
With InterWiz, we cut recruiter workload in half and can now handle hundreds of screenings effortlessly. Candidate evaluation is consistent, and top talent moves into training faster than ever.
Future Plans
Sybrid plans to extend InterWiz to outbound calling roles next, where communication clarity and performance under pressure are non-negotiable. The goal is to bring the same standardization and scale to outbound campaign hiring — consistent evaluation, no scheduling overhead, and no increase in recruiter workload as volumes grow.
