How do I interview in English in Switzerland?

Three different conversations, and how the advert gives them away

«Interviewing in English in Switzerland» is not one situation. It is three, and the advert distinguishes them for you before you apply. We counted the adverts open on SwissJobs.app on 23 August 2026 by what they ask for alongside English. The base is the adverts that state a language requirement at all — 72.7 per cent of the stock — and 41.1 per cent of those name English.

The first kind is English alone: 46.5 per cent of the English adverts. Here the whole process runs in English, from the first email to the draft contract, and your preparation is a professional one rather than a linguistic one. The one place it still breaks is the edges of the appointment — reception, the walk to the meeting room, the coffee — because those run in the language of the building, not the language of the meeting.

The second kind is English plus one national language: 32.6 per cent add German, 6.5 per cent French, 0.7 per cent Italian. In this group the switch is part of the process. It is also meant seriously. Where English and German are asked for together, German is wanted at professional level in 77.1 per cent of cases and at native level in a further 5.0 per cent; only 16.6 per cent settle for conversational. French is set slightly lower where it appears next to English: 61.0 per cent professional, 7.0 per cent native, 22.6 per cent conversational.

The third kind is English plus two or more national languages: 13.6 per cent. These are almost always roles with customers or sites across a language border. Expect the conversation to move — a panel that opens in English, changes into the language the job actually works in once the introductions are done, and comes back at the end for the practicalities.

The quickest way to place yourself is the language of the advert text. Among English-written adverts, 99.9 per cent name English and 70.4 per cent name nothing else. Among German-written adverts, 18.6 per cent name English and zero per cent name English alone. French-written adverts: 22.9 per cent name English, 0.4 per cent name only English. Italian-written adverts: 22.6 and 0.3 per cent. The asymmetry is the useful part — an English posting is a fair signal of an English process, while a German posting is a near-certain signal that it is not one.

Put the switch on the agenda yourself

The awkward moment in a bilingual interview is not the switch. It is the second before it, while both sides work out whether now is when it happens. You can delete that second by making the switch a scheduled item, and there are two good places to do it: the confirmation email and your own introduction.

In the confirmation email, ask which language the conversation will be held in and whether part of it will be in the local language. You learn two things at once — the answer, and, if the answer takes a while, that the company has not settled it internally. Both are worth knowing. And having it in writing lets you rehearse one thing properly instead of two things half-way.

In the introduction, put the level statement at the end rather than the beginning. Do the professional arc first, then one sentence on language: which language you work in daily, for how long, and where you slow down. «German B1 — I follow meetings, I still search for technical vocabulary» is something an HR manager can place on a scale. It also opens the door to the switch without anyone having to announce it as a test.

When the switch comes, go all the way over and stay there. The most common mistake is the hybrid — a local-language sentence propped up with English terms, then a retreat, then another attempt. That is harder to assess than two clean minutes with visible searching. And if you get stuck on a word, ask for it in the target language rather than routing around it. The question is itself a demonstration.

Keep in mind what the interview can and cannot settle. The requirement in the advert describes the job, not the appointment. If it asks for professional German and you are at B1, a good conversation does not change the requirement — but it does move the question from «can he» to «by when», and «by when» is a question you can answer with a date and a course.

Your interviewer is probably not a native speaker either

The most expensive assumption an international candidate brings into a Swiss interview is a native-speaking counterpart. The advert data says otherwise. Among the roles that ask for English, 1.9 per cent ask for native level. For comparison, among the roles that mention German at all, 2.5 per cent ask for native German. In both languages, native level is the rare exception — what is being bought is a skill, not an origin.

The official statistics point the same way. The Federal Statistical Office records that 12 per cent of the population have no national language among their main languages, and that English, Albanian and Portuguese are the three most common non-national languages. Nearly two thirds of residents aged 15 and over — 63 per cent — use more than one language at least once a week. Switching languages is not an unusual event here. It is the ordinary condition of the room, and it applies on both sides of the table.

What follows practically is that your English should be clear rather than impressive. Idioms, proverbs, irony and rapid interjections are a risk without an upside when your counterpart's English is a working second language. Short sentences, explicit numbers and a pace at which you are still thinking will do more for you. Candidates arriving from the United Kingdom, Ireland, the United States, Canada or Australia usually need to brake rather than accelerate — the habit of filling silence quickly reads, in this room, as difficulty listening.

Read the other direction too. If your English is not secure, pauses are not a flaw. A word that arrives after two seconds reads as care; a wrong word that arrives instantly reads as imprecision. And asking for a question to be repeated costs nothing at all — in a room where three people have three different first languages, everyone present has asked it.

Same job, different canton, different interview

Occupation is not the only thing that sets the language of the conversation. Location moves it again, and by a lot. To make the comparison clean we took a single field — IT roles whose titles point unambiguously at software, development, data or systems — and split it by canton.

In the canton of Zurich, 56.8 per cent of those IT adverts need no national language. In the canton of Bern, 15.4 per cent do. Same field, same titles, same stock of adverts, and an all-English process is close to four times as likely in one as in the other. Geneva sits at 73.7 per cent, Basel-Stadt at 47.6, Vaud at 33.3, Zug at 59.1, Aargau at 25.0. If you want to predict the language of an interview, read occupation and location together rather than one after the other.

The occupational spread is just as steep, measured across adverts that state a language requirement. Pharmaceuticals and life sciences ask for English in 72.7 per cent of adverts and for English alone in 44.2 per cent. Finance: 55.2 and 24.9 per cent. IT: 48.0 and 25.8 per cent. At the other end, nursing and care ask for English in 3.6 per cent of adverts, construction trades in 6.3, retail in 9.7. And where English does turn up in those fields, it almost never arrives alone: of the construction adverts that mention English, 85.7 per cent also want German at professional or native level, retail 76.3 per cent, commercial and administrative roles 79.0 per cent.

One more thing for your expectations. The English-hiring end of the market is not a short list of multinationals. Within the adverts where English alone is enough, the largest single employer accounts for 7.8 per cent and the ten largest together for 21.7 per cent; more than half of the employers involved have exactly one such advert open. The English process is widely distributed. It is simply not everywhere.

The words that stay German even in English

An English interview in Switzerland reliably contains a handful of terms with no clean translation, which is exactly why they are left in the original. Recognising them and explaining them in a half-sentence marks you as someone who has done the reading. Translating them creates misunderstandings that only surface at contract stage.

Pensum is the most important. Working time is negotiated as a percentage rather than in hours, and «80 per cent» is a contractual quantity, not a statement of intent. The Arbeitszeugnis is not a reference letter in the Anglo-Saxon sense but an owed, formalised document covering the whole employment. The Kündigungsfrist — the notice period — is a term with a statutory frame rather than something settled across the table. The Probezeit is its own section of the contract with its own deadlines. The 13. Monatslohn is part of the annual salary, not a bonus. The Referenzauskunft is a phone call to a named person, not a written testimonial.

Two practical consequences. When the salary question arrives in English, give an annual figure and say whether you are counting in twelve parts or thirteen; without that, the two sides are comparing different quantities and neither notices until later. When availability comes up, give a date and the notice period it follows from. Both fit in one English sentence each, and both save a second round of email.

It is worth noticing what the federal preparation guidance says about all this: nothing. The arbeit.swiss checklist for the job interview lists self-presentation, goals and expectations, why you applied, what you want to ask the employer, research on the company, the questions to expect, salary negotiation, and appearance and body language. The language of the conversation appears nowhere in it. Which makes it precisely what it is in the room as well: a matter the two people present sort out between them — and therefore one you are better off raising than waiting for.
