How do I practise a job interview with an AI voice?

Why speaking beats reading – especially in a language that is not yours

Most preparation is silent: you list your strengths, read typical questions, memorise a few lines. What fails in the room is rarely knowledge – it is form. Answers run three minutes when sixty seconds were expected, the structure collapses under a follow-up, and the salary question lands unprepared even though in Switzerland it is asked openly and early, often in the first conversation.

In Switzerland there is a second layer that generic interview advice ignores: the language. In our index of live Swiss adverts, roughly two postings in five are written in German and about one in five in English – so if you are applying from abroad or across a language border, the interview will usually happen in the advert's language, not in yours. A formulation that reads fluently on paper stumbles out loud, and you only discover that by actually speaking.

The classic advice – practise with a friend – has practical limits: the friend has not read the advert, asks too kindly, and is not available on a Tuesday night. A simulation asks as often as you want, always anchored in the specific posting.

Setting up the simulation: the job, the CV, the panel

Setup takes three steps. First the job: title, company, company size (1–5, 5–50, 50–200 or 200+ employees) and the advert – the real one, or a typical advert for your occupation if you want general practice. Second your CV: upload a file, pick one you saved earlier, or paste the text. Third the panel: you type freely who will be in the room – HR, a domain expert, your future manager, up to five roles – and choose the interview language: German, French, Italian or English.

Company size is not decoration. A five-person firm interviews differently from a corporation: broader questions, more hands-on, a far less formal register – in German-speaking Switzerland small companies often use the informal 'du' from the first minute, while a corporate panel runs structured competency questions. The simulation adapts its style and register to the size you set, which is worth experiencing once before it surprises you in the real room.

The questions are generated from your CV and the advert, not pulled from a catalogue. They name your actual positions and the posting's actual requirements, stay short the way spoken questions are, and are distributed across the panel by what each person would genuinely probe: HR asks about motivation, your reason for changing and your salary expectation (Lohnvorstellung – stating a figure is normal in a Swiss first interview), the expert digs into depth, and a role from a neighbouring team tests how you collaborate across that boundary.

What the live session is like

You start the session in the browser, allow the microphone, and hear the first question. You answer the way you would in the real meeting: freely spoken, no script. Everything you say is transcribed live, and that transcript is what gets rated. Then the next question follows – eight per session, each asked by the panel role it belongs to.

Swiss topics are treated as normal, because they are: salary expectations, Arbeitszeugnisse (the Swiss employer references that accompany most applications) and notice periods all belong in a Swiss first interview, so the simulation asks about them too. If you have never said a salary range out loud, it is better to do it here than for the first time in front of the real panel.

How to read your scores

Each answer receives a mark from 0 to 10, broken down into substance (is there anything concrete in it?), structure (is it ordered and of sensible length?) and fit to the role. It comes with two or three sentences of reasoning – and a note on what a strong answer would have included. That note is the real training value: you see the missing building block, not just a number.

At the end a report pulls it together: a pass probability in percent, strengths, concerns, and one note per panel role – what convinced the HR person, where the expert still doubts. If you redo the interview with the same configuration, the percentage stays comparable, so you can see in plain numbers whether the second run was better than the first.

What it costs – and exactly where free stops

You can start without an account: set up the session, see the first two questions and answer the first one. From the second question on you need a free account – an email address, no card. With the account you get five questions on the day you register, then five per month.

For regular practice there is a seven-day free trial, then CHF 15 per month or CHF 95 per year, cancellable any time. Even the subscription has a ceiling, because spoken AI minutes are the expensive part: up to ten sessions and 40 answered questions per month, 80 on the yearly plan, with the counter resetting on the first of the month. We state these limits deliberately – a price without its limits is half the truth.

What it cannot do

It hears you but does not see you: body language, eye contact, presence – none of that is assessed, and in a real interview it counts. The pass probability is a model's estimate based on the advert, your CV and your answers – not the employer's decision. Nobody can promise you an interview outcome, and a tool that promises one is selling you something.

The live transcript can mishear, especially proper names or strongly accented speech – what gets rated is what was understood. And the simulation does not research the company for you: knowing the employer's products, competitors and situation is an edge over the panel that no practice tool can replace.

Getting the most out of two or three runs

Practise with the real advert, not a generic one – it makes the questions specific, and the specific ones are the ones that hurt in the real meeting. Practise in the language of the advert: a German posting almost always leads to a German interview, whatever language the recruiter's first email was in. And repeat the same session after a day's gap rather than five times in a row – two or three runs where you actually read the reasoning beat ten mechanical ones.

If nerves are your real problem: most interview nervousness is unfamiliarity with the situation, and that is precisely what wears off when you practise out loud. The first spoken salary negotiation is always clumsy – better that it happens against an AI voice.

Template: a chat assistant plays the panel

Paste it in, add the advert and your CV, then answer, in voice mode if you can.

You are the interview panel for a job in Switzerland.
Role: [job title] at [company], company size: [number] employees.
In the room: [e.g. HR, future manager, specialist].
Language: [language of the advert].

Advert:
[paste advert]

My CV:
[paste CV]

Rules:
1. Ask exactly one question, then wait for my answer.
2. Eight questions: introduction, reason for moving, motivation, a situation, working with others, weaknesses, salary and notice period, my questions.
3. Do not comment on or praise my answers during the interview. Ask at most one short follow-up when an answer stays vague.
4. Only after question 8: score each answer from 0 to 10 on substance, structure and fit with the advert, with one sentence each on what was missing.

If the advertisement is in German, French, or Italian, write the prompt in that language as well, since the assistant tends to respond in the same language it was addressed in.

Before the first question: three settings that change the interview

First, the advert. Never practise in a vacuum. A real advert gives you the words the panel is listening for and the two or three requirements where you are weakest. Mark those before you start, because that is where the follow-up questions will land.

Second, the company size. Small Swiss firms, especially in German-speaking Switzerland, often switch to first names and the informal du within minutes, while a large employer keeps the formal register. If you are used to a UK or US interview, the difference is less about politeness and more about scope: a company of fifteen will ask what else you can take on, because everyone covers more than one job there.

Third, the language and the people in the room. Practise in the language of the advert. How much that varies by field shows in our own index: 28% of IT adverts ask for English only, against 1.9% in nursing. If you are moving to Switzerland for a non-IT role, assume the interview is in German, French or Italian unless the advert says otherwise. Then picture who asks what. HR covers motivation, reasons for moving and salary; the future manager asks about the work; a specialist digs into detail. Aim each answer at that person.

The round: eight questions in the order of a Swiss first interview

Question 1: Tell us about yourself. What they listen for: whether you get from your current job to this role in about a minute. Not your life since school, but three steps that lead to the advert and one sentence on why this role, now.

Question 2: Why do you want to leave your current position? What they listen for: a reason that points forward. Criticising your current employer lands especially badly in Switzerland, where the Arbeitszeugnis (the written employer reference every Swiss employee receives) and references will tell their own story anyway. Say what is missing and what this role offers.

Question 3: What draws you to this role with us? What they listen for: evidence you read the advert and know the company. Name one task from the advert and one thing about the company that is not in the first line of its website.

Question 4: Tell us about a time something went wrong and what you did. What they listen for: situation, your task, your action, the result, in that order. The most common miss is a story with no result. End on what changed afterwards.

Question 5: How do you work with people who disagree with you? What they listen for: whether you can reach agreement. Swiss teams often decide by broad consensus, which surprises people from flatter or more top-down cultures. An example where you persuaded someone, or were persuaded, beats a claim that you are a team player.

Question 6: What are your weaknesses for this role? What they listen for: honest self-assessment. Pick a real gap against the advert and say what you are already doing about it. Perfectionism as a weakness is read as dodging the question.

Question 7: What are your salary expectations, and when could you start? What they listen for: whether you can say a number without hesitating. It is normal in a Swiss first interview. Give a yearly range, say whether it includes a 13th monthly salary, and state your notice period. Swiss notice periods are often longer than candidates from abroad expect, so know yours. If you stall here, practise this one twice.

Question 8: Do you have any questions for us? What they listen for: interest in the work, not in holidays. Two questions about onboarding, the team, or what success looks like after a year are enough. Having none reads as having no interest.

After each answer: the three-point check

Record the answer on your phone and play it back straight away, before reading on. Then ask yourself three things. Substance: was there an example, a figure, the name of a project, or only adjectives? Structure: did the answer start and finish, or did it circle? Fit: did a term from the advert appear, and was it clear why it matters for this role?

Rate each point honestly. Where one is weak, say the answer again immediately, fixing only that one thing. That second version is where the practice pays off. A question that works first time does not need repeating today.

Watch the length too. If you get impatient listening to yourself, it was too long. In a real interview nobody interrupts you; they simply stop listening.

If you ask a chat assistant instead

A language model can play the panel, and it usually costs nothing. The weakness is the rhythm. Without clear instructions it comments on every answer at once, praises too generously and never follows up. You end up rehearsing a coaching session, not an interview. The template below therefore holds all scoring back until the end.

Another significant flaw is that text boxes primarily foster written communication, rather than spoken expression. To bridge this gap, consider using voice mode, if available, or articulating each response out loud before typing it down.

The round with a voice, a panel and a score

The live version on SwissJobs.app faithfully replicates the three settings outlined earlier: the job posting, company size categorized into four tiers, maximum panel size of five, and options for interview languages German, French, Italian, or English. Eight questions are crafted from your CV and the job posting, each posed by a panel member based on its role. During the live conversation, the voice maintains a neutral stance, akin to a genuine panel, refraining from coaching or scoring.

Afterwards each answer gets a mark from 0 to 10 with the reasoning, and a report sums up the interview with an estimate in per cent. The first question needs no account. A free account gives five questions on the day you sign up and five a month after that. The subscription, after a seven-day trial, is CHF 15 a month or CHF 95 a year, with up to ten rounds and 40 questions a month, or 80 on the yearly plan.

The percentage is an estimate from the advert, your CV and your answers, not a forecast of the employer's decision. It is useful for comparing a second round with the first, and for nothing more.

When a person is the better practice partner

Both the round on this page and the live version only hear what you say. Eye contact, handshake, how you sit: neither sees any of it. If your problem is presence rather than content, practise with a person, ideally someone who is not your closest friend.

For senior roles, assessment centres with role plays, or a move into a new industry, a professional interview coach or someone already in the target job is worth it. They know the unwritten expectations of the sector that no advert states. If you are registered with the RAV, the regional employment office, ask there about interview courses before paying for one yourself.

And if you only want a quick warm-up, you need neither a subscription nor a coach. The eight questions above, aloud and against a timer, are a complete round.
