The short answer: if a job requires two languages, expect the employer to test them, not just take your word for it. That can mean switching languages partway through the interview, a separate oral assessment, a written translation, or a role-play with a “customer” in the second language. Prepare by describing your level honestly on your resume, preparing your key answers in both languages (as natural answers, not word-for-word translations), building a vocabulary list for the job, and practicing out loud in both languages, including switching between them.

Why bilingual skills are in demand
Many employers need staff who can serve customers, patients or students in more than one language. In the United States, the Census Bureau reports that the number of people who spoke a language other than English at home nearly tripled from 23.1 million in 1980 to 67.8 million in 2019, almost 1 in 5 people. Customer service, healthcare, education, government, sales and international business roles often list a second language as required or preferred.
What to expect in a bilingual interview
| Format | What happens | How to prepare |
|---|---|---|
| Language switch | The interviewer changes language partway through, often without warning | Practice moving between languages mid-conversation |
| Full interview in the second language | Some or all questions asked in the second language | Prepare your core answers in that language |
| Oral proficiency test | A separate conversation with a native speaker or a scored phone or video test | Practice speaking on everyday and work topics for 10 to 20 minutes |
| Written translation | Translating an email, notice or document | Practice translating real work documents accurately, not literally |
| Role-play | Handling a customer, patient or caller in the second language | Rehearse the most common situations for the role |
| Interpreting exercise | Relaying a conversation between two people | Practice summarizing accurately in both directions |
Describe your level honestly
Overstating your level is the fastest way to fail a bilingual interview, because it will be tested.
- Use clear terms: native or bilingual, fluent, professional working proficiency, conversational, basic. Many employers and schools also use frameworks such as the CEFR scale (A1 to C2); if you have a certificate or score, list it.
- Be specific about skills: “Fluent spoken Spanish; professional written Spanish” is more useful than “Spanish.”
- Give evidence: where you used the language at work, study abroad, certificates, or volunteer work.
How to prepare
- Prepare core answers in both languages: tell me about yourself, why this role, your strengths, and two or three stories. Write them in each language naturally rather than translating line by line, because direct translations often sound stiff.
- Build a job vocabulary list: terms for your field (products, procedures, medical or legal terms, software), plus numbers, dates and money, which are easy to fumble.
- Practice switching: have a friend or practice tool change language mid-answer.
- Learn the register: formal vs informal address (such as usted vs tú in Spanish or vous vs tu in French) and polite phrases for customers.
- Practice out loud and record yourself: listen for pace, clarity and filler words in each language. See our guides to improving your English pronunciation for interviews and job interviews in English for non-native speakers.
Common bilingual interview questions
“How did you learn your second language, and how do you keep it up?”
“I grew up speaking Portuguese at home and English at school, so I’m fluent in both. I studied business Portuguese at university and use it weekly with clients in Brazil, which keeps my professional vocabulary current.”
“Tell me about a time you used your language skills at work.”
“A patient’s family only spoke Spanish and was worried about a discharge plan. I explained the medication schedule in Spanish, checked their understanding by asking them to repeat it back, and flagged that a qualified medical interpreter should join the follow-up call for the detailed instructions. The family thanked the team, and the nurse manager asked me to help translate our discharge checklist.”
More questions
- “Can you answer the next question in [language]?”
- “How would you greet and help a customer who only speaks [language]?”
- “How would you explain [a product, policy or procedure] in [language]?”
- “Please translate this email / notice.”
- “What would you do if you didn’t know a word during a conversation with a customer?”
- “How comfortable are you writing in [language] compared with speaking?”
- “Have you ever interpreted for others? How did you make sure it was accurate?”
If you blank on a word
It happens to everyone, even native speakers. Describe around it (“the document you sign when you buy a house”), ask to confirm (“Do you mean the deposit?”), or say you’ll check for anything technical. Interviewers are judging whether you can communicate clearly and handle gaps calmly, not whether you know every word.
Cultural norms
Language and culture go together. Learn the expected formality, how directly people disagree, how interviews usually open and close, and small courtesies in the culture of the language you’ll be using. If you’re interviewing for a job abroad, see discussing relocation and salary when moving and working remotely from another country.
Role-specific tips
- Customer service and sales: practice greetings, de-escalation phrases and explaining policies. See handling difficult customer interactions.
- Healthcare: know common medical terms, and know when a qualified medical interpreter is required instead of an ad hoc one.
- Education: be ready to explain how you’d communicate with families and support students learning the language.
- Translation and interpreting roles: expect formal tests of accuracy, terminology and ethics.
