Language requirements in job postings are often written vaguely, "good English," "fluent German," "working knowledge of French." These phrases mean different things to different hiring managers and create inconsistent screening. A CEFR-based approach gives everyone a shared vocabulary and reduces the risk of hiring someone whose language level does not match the role.
Setting the right language requirement
The first step is matching the CEFR level to what the role actually requires. Overstating the requirement excludes qualified candidates. Understating it creates problems after hiring.
B1 is sufficient for roles involving occasional written communication in a second language, reading emails, writing short reports, understanding instructions. B2 covers most customer-facing international roles, team meetings in a second language, and professional correspondence. C1 is needed when the candidate must persuade, negotiate, or present in the second language without significant preparation time. C2 is rarely required in business contexts and should only be listed when the role involves legal, literary, or highly precise language work.
| Role type | Recommended CEFR | What it covers |
|---|---|---|
| Admin with occasional emails | B1 | Reading and writing routine correspondence |
| Customer service (international) | B2 | Handling calls and emails confidently |
| Account manager (international clients) | B2-C1 | Negotiation, presentations, relationship management |
| Legal or financial services | C1 | Precise written and spoken accuracy |
| Translation or interpretation | C2 | Near-native mastery |
Screening methods, what works
Verifiable certificates at the application stage give you an objective, comparable data point across all candidates. Asking candidates to provide a certificate shifts the cost to them and saves screening time. A certificate that cannot be verified is treated the same as a self-reported level.
A practical language task at the interview stage confirms the certificate result in the work context. This can be as simple as asking the candidate to describe their experience in the target language for five minutes, or sending a short email task before the interview. The purpose is not to catch people out but to confirm that the level holds under work conditions.
Interview in the target language for at least part of the session. A candidate who holds a B2 certificate but becomes halting and monosyllabic when the interviewer switches to that language is signalling a gap between their certificate level and their operational fluency.
Common mistakes in language hiring
Requiring "native speaker" when B2 or C1 is sufficient. In most EU countries, specifying native speaker without genuine justification is a discrimination risk. The functional level, what the role needs, is the appropriate standard.
Accepting self-reported levels without verification. Research consistently shows self-reported language levels are inflated by approximately one CEFR level on average. A candidate who writes "C1 English" on their CV may test at B2.
Testing only reading and writing. Many roles require spoken fluency. A written test alone does not confirm the candidate can hold a phone call or lead a meeting in the target language.
