How to verify foreign language knowledge during recruitment?

„"Very good command of English"—this phrase appears on every other CV. In practice, it means a B1 level, which is barely sufficient for reading emails, or fluent communication in an international environment. A recruiter who doesn't check this beforehand will learn the truth at the worst possible moment—when the new employee has to take a call from a foreign client.

The problem isn't new. But companies still ignore it—or verify language so superficially that it's pointless. A few questions in English at the end of the interview aren't verification. It's a checkup to see if the candidate can speak a few sentences in a comfortable situation.

Why does language level in a CV mean nothing?

Language scales are subjective. A candidate who writes a B2 might have a B1 or a C1—and both will write exactly the same thing on their CV. No one verifies this at the submission stage, so candidates can write whatever they want.

But even assuming someone assesses their level honestly, "good English" in everyday conversation is something completely different from professional English. Someone can chat comfortably about their weekend in English and yet have serious trouble writing a complaint email to a foreign client or conducting negotiations over the phone.

Before you begin verifying candidates' language skills, answer one question: what exactly will this language be needed for? Reading documentation is one requirement; delivering a presentation to a foreign board is quite another.

How to Test Your Foreign Language Knowledge - What Actually Works

Simulation of a professional situation in a foreign language

The best method I know. Not because it's complicated—precisely because it's simple and direct. A customer service candidate conducts a simulated conversation with a foreign customer who has a problem. An account manager candidate conducts a portion of a sales conversation in English.

It all comes down to this. Language proficiency, yes, but also whether the candidate can actually achieve anything in the conversation. You can have excellent grammar and completely lose the plot when the client starts getting nervous. Or you can make a lot of mistakes but still conduct the conversation confidently and effectively. Which of these two is necessary depends on the position.

Written assignment

For positions where email communication is essential, it's a must. Speaking and writing are different skills and rarely go hand in hand. A candidate who speaks English fluently may write with errors that would be embarrassing in emails to clients. And vice versa.

The scenario for a written assignment should be close to the realities of work. A response to a complaint, an email with difficult information to a client, a brief summary of a meeting. 15-20 minutes is enough to demonstrate the level of skill.

Part of the recruitment interview in a foreign language

The simplest and most commonly used solution. The recruiter switches to the foreign language and conducts part of the conversation in that language. This provides a quick impression of ease and fluency.

But it has one major limitation: the recruiter evaluates subjectively. A candidate who speaks confidently and loudly receives a higher score than a candidate who speaks more slowly but precisely—regardless of the actual level. Without established evaluation criteria, results are not comparable between different recruiters or different days.

Standardized language tests

IELTS, TOEIC, and Cambridge certificates provide objective, comparable results. This is useful when a company recruits a large number of candidates and wants to maintain consistent standards.

A caveat: a five-year-old certificate with two years of no experience is a completely different level than a fresh certificate. Treat it as a starting point for verification, not a replacement.

Conversation with a native speaker

In positions where language is absolutely critical—regular presentations to foreign management, negotiations, working in a fully English-speaking environment—a recruiter who isn't fluent themselves won't accurately assess a candidate at a C1-C2 level. Engage someone who can truly appreciate the nuances.

Mistakes that companies make when verifying language

Certificate as the only criterion

A certificate from four years ago, two years without practice—that's not the C1 level you'd expect at the exam. Certificates get old, especially if the candidate hasn't actively used the language. Treat them as a signal to begin the assessment, not the end of it.

The recruiter evaluates a language he doesn't know well himself.

A recruiter with a B2 level assessing a candidate at C1 level is a recipe for error. A candidate who uses advanced vocabulary and complex structures may be given a lower rating because the recruiter "doesn't fully understand" what they're saying. If the position requires advanced language, engage someone with the appropriate competencies to assess them.

Testing only one skill

Just an interview, no written component. Or vice versa. If the position requires both, check both. These are two different competencies that don't always go hand in hand.

Lack of professional context during verification

A general conversation in English about a candidate's experience won't tell you whether they'll be able to handle a foreign customer's complaint. Verify language in the context it will actually be needed—not in the abstract.

What language level is required for different positions?

Occasional email correspondence with foreign partners—B1-B2 is perfectly adequate. Regular conversations with foreign clients—at least B2, preferably C1. Presentations to foreign management, negotiations, and daily work in an English-speaking environment—C1-C2. Define this specifically before you begin recruiting. "Good command of English" in a job ad isn't enough—for both candidates and recruiters.

FAQ – most frequently asked questions about foreign language verification in recruitment

How to check a candidate's foreign language knowledge?

This can be achieved through a simulated work situation in a foreign language, a written assignment if the position requires correspondence, or a standardized test. The method should be tailored to the actual job requirements—not every position requires a full language test.

Is a language certificate sufficient for verification?

As a starting point, yes. As a sole criterion, no. The certificate may be outdated, may not reflect the professional language needed for the position, and says nothing about how the candidate communicates under pressure. It's worth verifying it practically independently of the certificate.

How to assess a foreign language when the recruiter is not fluent himself?

Standardized tests provide objective results regardless of the recruiter's competence. Alternatively, a recorded simulation can be assessed by someone with higher language skills, who may not be involved in the entire recruitment process.

How to verify language during mass recruitment?

Automated interview simulation tools enable high-volume language verification without a proportional increase in recruiter time. Candidates undergo a foreign language simulation, the system assesses their communication skills, and the recruiter analyzes the results.

What level of English is required for recruitment?

Depends on the position. Occasional correspondence—B1-B2. Regular conversations with foreign clients—B2-C1. Presentations and negotiations in English—C1-C2. Define requirements clearly before you start recruiting—for both candidates and recruiters.

Summary

A CV's language level is just a declaration. Without practical verification, it means nothing. The best method is to simulate a professional situation in a foreign language—because it simultaneously tests the candidate's language level and whether they can actually achieve something in the interview. This is done in a difficult situation, under pressure, and in a context that will be relevant to the job.

The rest—certifications, general interviews, tests—make sense as supplements. Not as the sole verification method.
