You have the experience. You have the CV. You have, on paper, exactly what they are looking for.
Then the interview starts — in German, or French, or Spanish — and somewhere between "Tell me about yourself" and "What are your greatest strengths?", your brain goes very quiet.
You know the answer. In English, you've given this answer a hundred times. You have anecdotes, specific numbers, a punchline. You're good at this.
But right now, in this language, you are saying: "I work very much in team. The results were... good."
The interviewer nods politely. You know exactly how this is going to go.
The problem was never your professional ability. The problem was your professional vocabulary. And unlike tourist vocabulary — restaurants, directions, polite small talk — professional vocabulary is almost never covered in language apps or evening classes.
Nobody taught you how to say "I streamlined the procurement process and reduced lead times by 23%" in Italian. They taught you how to ask where the train station is.
Why Professional Vocabulary Is Different
Everyday vocabulary gets you through life. Professional vocabulary gets you through a career.
The gap between the two is enormous, and it sneaks up on you. You might have a solid B2 level — you can watch TV, manage daily life, chat with colleagues informally — and still fall completely apart when asked to describe a strategic initiative or explain why you left your last role.
This is because professional language has its own register. It uses specific verbs (to spearhead, to oversee, to implement, to drive), specific structures ("In my previous role, I was responsible for..."), and specific frameworks ("The situation was X, I did Y, and the result was Z"). All of this has to be available to you automatically, not translated painfully word by word.
Under interview pressure, you do not have time to translate. If the words aren't ready, they won't come.
The Four Vocabulary Areas That Win Interviews
1. Your story vocabulary Every interview starts with some version of "Tell me about yourself." You need to be able to narrate your professional history fluently in the target language. Write out your career story — not a script, but the key phrases. How did you move from role to role? What were your main responsibilities? What are you proud of?
Learn the transition phrases: "After three years at X, I moved to Y, where I was responsible for..." These become the backbone of your answer.
2. Achievement vocabulary Interviewers want numbers and outcomes. Learn the vocabulary for talking about impact: increased, reduced, improved, launched, managed, led, delivered. Learn how to quantify: percentages, team sizes, budgets, timelines. The sentence "I led a team of eight and delivered the project two weeks ahead of schedule" is worth ten general claims about being hardworking.
3. Industry vocabulary This is where most learners are completely unprepared. Every industry has its own lexicon. Finance has different words from logistics, which has different words from healthcare. Spend time with job postings in your target language — the actual requirements and responsibilities sections. Those words are the ones your interviewer uses every day. Use them back.
4. The difficult questions "What is your greatest weakness?" "Tell me about a time you failed." "Where do you see yourself in five years?"
These questions have a specific vocabulary of honesty, reflection, and professional growth. Phrases like "I've learned that...", "In hindsight, I would have...", "That experience taught me to..." These are the moments that distinguish candidates who are genuinely thoughtful from candidates who sound like they memorized a script.
The Preparation That Actually Works
Generic vocabulary practice won't cut it. You need to build your specific professional vocabulary in the target language — the words that belong to your industry, your role, and your particular story.
Start with the job posting itself. Take every verb and noun in the requirements section and make sure you can use each one in a sentence about your own experience.
Then write out your five strongest professional stories — the STAR situations (Situation, Task, Action, Result) you'd want to tell in any interview — and translate them properly. Not word for word, but idiomatically. What would a native speaker say here?
Use Vokabulo to capture every new professional phrase as you encounter it. When you read a French article about your industry and spot a phrase you'd want to use, save it in context. When you draft your interview answers and look up how to say something properly, save that too.
By interview day, you want those phrases already in your long-term memory — not in a notebook you review once the night before.
On the Day
A few things that help in the room itself.
Slow down. Non-native speakers almost always try to rush, which leads to mistakes and anxiety. Slowing down makes you sound more confident, not less fluent.
Ask for clarification. "Could you clarify what you mean by...?" is not a sign of weakness. It is exactly what smart, careful professionals do. And it buys you five seconds to think.
Don't apologize for your language. Unless you make a specific error worth acknowledging, never start a sentence with "Sorry, my German isn't perfect, but..." It frames everything that follows as inadequate. Start with the answer.
The interviewer is not assessing your grammar. They are assessing whether they want to work with you. Vocabulary and confidence will take you much further than perfect syntax.
