If I were choosing an agency today, I’d start by checking how they think, not how they sell. I once sat through a pitch where the agency promised speed, speed, speed. When I asked how they assess empathy or handle roleplays, they went quiet. That was a red flag. The agency you want should be able to explain their screening in plain language: what they test, why it matters, and how it connects to your actual customers.

Here’s a practical checklist I’d use. First, ask for a sample scorecard, and make sure it includes both hard skills (typing speed, CRM experience, compliance awareness) and human skills (tone, resilience, curiosity). Second, ask how they manage attrition risk, because a candidate who stays is often more valuable than a candidate who starts quickly. Third, ask how they keep you honest too, like whether they will push back if your salary band or shift pattern is unrealistic. Fourth, ask how they’ll keep candidate experience strong, because great people drop out when processes drag.

The information here helped me get a better grasp of the topic. Just to add, trust your gut on communication: if they are vague now, they’ll be vague when things get tough.
