A contact centre hires in every language it serves. Screening in only one of them quietly selects for fluency in the assessment language, rather than for the skill the role actually needs.

Vessik, a telecom operator, ran every screening round in the one language its screeners shared, for entirely practical reasons. The candidates it lost to that choice were rarely the ones who lacked the skill for the queue they had applied to.

A filter nobody intended

Candidates who would handle a customer confidently in their own language came across as hesitant in the round that decided whether they got the job. That hesitation had little to do with how well they would actually do the job once hired. The centre was, in effect, hiring for its screening process rather than for its queues.

Vessik’s queues run in six languages. Its screening ran in one. Nobody had set out to build that mismatch. It was simply the language the interviewers already spoke, and nobody had costed what that convenience was quietly filtering out.

Six languages, one standard

Vessik uses Yardstick Agents to screen applicants in the language they applied in, against the same criteria in each. Fluency in the assessment language stops being a hidden filter. The assessment language is now whichever one the candidate already uses.

The criteria were translated once, then reviewed by a fluent speaker of each language. A rubric that drifts in translation reintroduces the exact problem it was meant to remove. Where a role genuinely requires a second language, that is assessed as its own separate criterion, and named as one.

Screenings come back into one structured record, regardless of which language they ran in. A team lead comparing two candidates is comparing answers, not translations.

A screener still makes the call

Screening in six languages does not remove the human step. A reviewer reads every transcript and assigns the score. The tool only guarantees that the criteria being read against are the same ones used in every other language. Nothing is advanced automatically and nothing is rejected automatically. The reasoning behind each score stays attached to the record, in whichever language the screening happened.

What screening in six languages changed

Vessik now screens contact centre applicants in 6 languages, against one shared standard rather than six adapted ones. That was the point of the change, not an incidental benefit of it.

100% of the criteria used across those languages were reviewed by a native speaker before they went live. A phrase that read as confident in English, but hesitant in translation, was caught before it ever reached a candidate.

Candidates who screen in their own language are advancing +35% more often since the change. The one step still done by hand is the second-language assessment itself, for roles that genuinely need it. A human reviewer judges that conversation directly.

Applying the same standard to onboarding

Vessik is now reviewing its onboarding materials for the same mismatch. Several of those are still written in the one language the original screening ran in.
