Optimise your CV for the ATS, or write it for a human?

Writing for the ATS or for the reader

The two goals conflict far less than the guides claim. And in Switzerland the question is smaller: incoming professionals regularly report Swiss recruiters recommending a designed document and a photo — the filtering layer is not as universal here as in large Anglo-Saxon markets.

Who opens your CV first, and how to tell in advance

Before optimising a document, it is worth asking who opens it. We traced where the apply links of the jobs open on SwissJobs.app actually go. 52.5 per cent point at an address belonging to the employer, 31.1 per cent at a recognisable applicant system, 16.4 per cent at another job board. The largest single block is the company, not the machine — and that is precisely where the Swiss market differs from the one most ATS guides describe.

What predicts the difference is not your CV but the advert. Language separates most sharply: English-written adverts route into a system 59.2 per cent of the time, German-written ones 24.4 per cent, French-written ones 17.7 per cent. That is a factor of three between an English and a French posting in the same country. Apply in French in the Romandie and in more than four cases out of five there is no purchased system at all.

Place and occupation move the same way. Zurich region 43.9 per cent, Geneva and Vaud 36.3, Bern 28.9, Basel 28.4, Ticino 20.8, eastern Switzerland 20.3 per cent. By field: logistics and transport 38.2 per cent, nursing and care 32.1, construction and trades 28.6, hospitality 21.0, retail 11.6 per cent. Retail is the instructive case — it has the fewest applicant systems and the most job boards, with 45.4 per cent of its apply links going to a marketplace rather than to software.

The address promises more than it delivers

A link to a company domain does not mean no software is running. Plenty of employers host their application portal on their own address — jobs.example.ch — with purchased software behind it. So we checked rather than assumed: 70 adverts pointing at an employer address, one per employer, spread evenly across the list, opened on 25 August 2026, with the delivered page source searched for the names of around sixty recruiting systems.

69 of the 70 opened. 58 per cent of them named a system in the source — SuccessFactors most often, then Workday, Teamtailor, Oracle, Umantis, Prospective, Rexx and others. The share with some software behind it is therefore clearly higher than the share you can spot from the address. We publish that even though it blunts our own point: anyone claiming that in Switzerland a human almost always reads first has not opened the pages.

Narrow the frame and the picture turns again. Of the 21 pages on a .ch address — Swiss firms, clinics, municipalities — 42.9 per cent named a system, and 23.8 per cent still carried an e-mail address for applications in the middle of the page. Roughly a quarter of those pages had no system and a visible mailbox: a town administration, a construction firm, a hotel, a consultancy. Two limits belong with the number: 70 pages are a sample, not the market, and a fingerprint in the source proves that software is involved, not what it does.

What a Swiss applicant system says it does

Rather than guess what happens behind the form, you can read the vendors. Ostendis, a Swiss e-recruiting provider that hosts on its own infrastructure, lists its features publicly. Under receiving applications, on 25 August 2026, it names several application channels, «E-Mail Bewerbung», automatic job assignment, duplicate-application detection, virus and trojan scanning, and «CV Parsing». It also claims to be the only e-recruiting system that does not require a form at all — applications still arrive by e-mail or by post.

What is missing from that list matters more. There is no automatic score, no ranking, no cut-off that removes candidates. The selection features are called a short assessment and simple candidate evaluation: tools for humans reading dossiers. Even the rejection is an act of the company — bulk rejections, the vendor says, are done in a moment. The homepage states the purpose of the system as relief rather than selection: more time for the human core of the job, and a reduction in administrative effort of up to 64 per cent according to the vendor's own customer study.

The same list includes an interface to the RAV, the regional employment centres — a detail no English-language ATS guide mentions, and a good indication of how local these systems are. The practical rule for you: CV parsing means the software lifts your name, your positions, your dates and your contact details out of the PDF and into fields. It can fail at that. It does not send the rejection.

Swiss law treats the purely mechanical decision as a special case too: Art. 21 of the Federal Act on Data Protection obliges the controller to inform a person about a decision reached exclusively by automated processing that considerably affects them, and that person may request review by a natural person. Whether a rejection in a hiring process meets that narrow threshold is a legal assessment of the individual case. The point here is only this: fully automatic filtering is not the normal case in Swiss law, it is the case that comes with a duty to inform.

The five places where the two readers genuinely disagree

First, the combined PDF. arbeit.swiss expects a dossier with work references, diplomas and certificates, complete and in chronological order, and says all documents should be summarised in a PDF file. Generic ATS advice says the opposite: one lean file, the CV only. The form itself settles it. Separate upload fields for CV, letter and references means upload separately. A single field means combine — but with the letter and the CV on the first pages, not behind twelve pages of Arbeitszeugnisse (the Swiss employer references).

Second, the photo. The English version of the arbeit.swiss page lists personal details «including photograph» without qualification, as do the French and Italian versions; the German version says «gegebenenfalls», if applicable. In Switzerland a photo is convention, not a mistake — unlike the American resume rule you will have read. For the machine an image is harmless as long as it carries no text: put your name, phone number and address inside a header graphic and you lose exactly the fields parsing looks for. Picture yes, text inside the picture no.

Third, columns, tables and text boxes. Here the machine wins outright, because the human loses nothing: a two-column CV looks tidy on paper and comes out of a parser interleaved. One column, plain headings, month and year at every position. Fourth, keywords. Taking the advert's own terms is sensible as long as they are true of you. A word list at the foot of the page does not reliably help the software and costs you credibility with the person immediately. And nothing can be guaranteed: what any individual filter does is not visible from outside.

Fifth, the Swiss fields no parser has a box for: the permit line — B, C, G, or registration after the start date — the Pensum as a percentage, CEFR language levels, and the run of Arbeitszeugnisse. Here the human wins, and the fix is cheap: write them as ordinary text in the CV, each on its own line. The software then reads them as text, and the person deciding finds them where they expect to. One more detail arbeit.swiss names explicitly, and it serves both readers: clear and correct file names.

Can you tell from the employer? Barely

The common rule of thumb says small firm, therefore a person; large group, therefore a machine. We grouped the adverts by how many open positions each employer has, and the rule of thumb does not hold. Employers with a single open advert — 45.2 per cent of all advertisers, but only 6.9 per cent of the adverts — route into an applicant system 25.9 per cent of the time. Employers with six to twenty adverts reach 37.1 per cent. The difference exists, but it is small.

At the top end the rule inverts. The sixteen largest advertisers together account for 24.9 per cent of all adverts and route into an applicant system only 21.7 per cent of the time — but to a job board 55.5 per cent of the time. The ten largest carry 21.5 per cent of adverts at a system rate of 17.4 per cent. Their vacancies reach you through a marketplace, and that is where the application starts too.

Across every size band the system rate therefore sits between 22 and 37 per cent. The size of the employer tells you almost nothing; the language of the advert tells you a great deal. To know what you are walking into, look at the apply link and at the language the advert is written in, not at the size of the name above it.

If you are relocating, or already here on a permit

The single largest gap between an international CV and a Swiss dossier is not formatting, it is completeness. A Swiss application is expected to arrive with the work references from every previous employer, complete and in reverse chronological order. Nobody tells arriving applicants this, and no parser asks for it. If your previous employers were abroad and never issued such a document, say so in one line rather than leaving a hole where the stack should be.

Three more fields belong in the CV and nowhere in a template you download from a global site: your permit status as its own line, your availability, and the Pensum you are looking for in per cent — 80 per cent, not four days. State language skills as CEFR levels, B2 or C1, rather than «fluent»; the advert usually states its requirement the same way, which makes the comparison mechanical for both readers.

And keep the Swiss terms rather than translating them into American equivalents. It is a CV, not a resume. Salary in Switzerland comes with a thirteenth month; holiday is Ferien; a Zwischenzeugnis is an interim reference. Writing them as they are read here is the cheapest signal in the document that you understand where you are applying — and it costs the parser nothing.

The answer, sorted by case

English-language advert from an international employer in Zurich, Basel or Geneva: expect a system. Take the advert's technical terms literally, keep the document to a single column, upload only what the form asks for. This is the group the standard ATS advice was actually written for, and for you it is largely right.

German or French advert from a company, a clinic or a municipality: expect a person to open the dossier, and expect them to want it complete. Completeness beats keyword density here. If the advert carries an e-mail address, the question has answered itself.

And when you cannot tell, which is the normal situation: write the CV for the person, then have the mechanical half checked — readability, completeness, the advert’s own terms. The order is the whole trick. A document written for a human almost always survives the machine; a document built for the filter fails with the person — and the person is the one deciding.
