The cover letter mistakes that sink an application in Switzerland are almost always the same ones: a generic letter sent to everyone, empty phrases with no concrete content, an overly rhetorical tone imported from France, the slightest spelling mistake, a length that runs past a single A4 page, and a passive ending along the lines of "I remain at your disposal." A recruiter spends about thirty seconds on an application on average: a letter that says nothing specific about you or about the company is set aside before it is ever really read.
"I sent forty letters and got no replies." Often, the problem is not the background, it is the letter. In French-speaking Switzerland, it plays out on precise codes, and a few mistakes are enough to tip an application from the good side of the pile to the bad one.
One honest point first: a perfect letter will never rescue an off-target CV. The CV is still what decides, the letter serves to separate candidates. But the reverse is true as well, and that is where it hurts: a sloppy letter can sink a good application. The mistakes below therefore cost you more than a fine letter earns you.
The good news is that these mistakes are well known and avoidable. In this article, we review the most common cover letter mistakes, what they actually cost you, and the good practice to apply instead, with the Swiss angle every time.
What is the worst mistake in a cover letter?
The worst one, the one that costs you the most, is the generic letter. A letter that could be sent to any company without changing a single word motivates no one. A too-ordinary application and an apparent lack of motivation are, in fact, among the reasons for rejection recorded on the Swiss side (jobup.ch): a one-size-fits-all letter ticks both boxes.
A recruiter spots a generic letter immediately: no company name, no reference to the job posting, interchangeable sentences. The signal it sends is a bad one: "I apply everywhere, without conviction."
Conversely, an effective letter shows that you have understood the role and the company. Two or three concrete elements are enough: a specific responsibility from the ad, a value the company promotes, a recent project you mention. This mirrors the approach that works for the CV, which also needs to be calibrated posting by posting, as we explain in tailoring your CV to each posting.
Which phrases should be banned?
Empty phrases give the illusion of writing while saying nothing. "Driven by a genuine passion for your sector," "blessed with excellent people skills," "dynamic and motivated": the recruiter has read them a thousand times, and they provide no proof at all.
The Swiss rule is clear: replace the adjective with the fact. Rather than claiming you are "rigorous," show it with an example or a result. This principle also applies to the CV, where action verbs work far better than self-proclaimed qualities.
| Phrase to avoid | Why | What to write instead |
|---|---|---|
| "Driven by a passion for your sector" | Cliché, unverifiable | A specific, concrete reason for targeting this role |
| "Dynamic, motivated and rigorous" | Adjectives without proof | A fact or a result that demonstrates it |
| "I believe I match the profile" | Hesitant, timid | "My experience in X directly answers your need for Y" |
| "I remain at your disposal" | Passive, waiting | "I would be glad to discuss this with you in an interview" |
| "Following your advertisement, I take the liberty of..." | Worn-out opening line | A direct hook about the role or the company |
Is a French tone a problem in Switzerland?
Yes, and it is a common mistake among candidates coming from France or trained in French codes. The Swiss cover letter is more direct and less rhetorical than the French one. You get to the point, you avoid long literary flourishes and convoluted turns of phrase.
Three differences in tone to keep in mind:
- Restraint comes first. No superlatives, no heavy flattery. A Swiss recruiter values clarity and measure.
- Proof before emotion. You lay out what you can do and why it is useful to the company, rather than a long tale about your calling.
- Language skills matter. Depending on the role and the region, mentioning your level of German, English or French can make the difference. This is a point often overlooked by candidates coming from France.
On the other cultural differences between the two markets, our article Swiss CV vs French CV details the gaps that also matter for the letter.
Is a letter that is too long a dealbreaker?
Often, yes. The norm in Switzerland is one A4 page maximum. A concise letter shows that you respect the recruiter's time and that you can synthesise. Beyond one page, you dilute your message and risk not being read all the way through.
This is all the more true because reading time is short. Studies on the subject estimate that a recruiter spends about thirty seconds on an application during the first screen (DOCaufutur). In other words, a letter that does not get straight to the point does not have time to convince.
That does not mean the letter is pointless, quite the opposite. More than half of the recruiters surveyed feel that the cover letter influences their hiring decision (CVGenius survey). A good letter, short and targeted, remains a real lever, as long as it is legible at a glance.
Do spelling mistakes really count against you?
A great deal, and with no appeal. A single mistake in a letter is often enough to send a signal of carelessness, especially in French-speaking Switzerland where command of the language is seen as a marker of seriousness. On a first screen, when several applications are equally strong, spelling makes the difference, in the wrong direction.
The points to check before sending:
- Spelling and grammar, proofread with fresh eyes, ideally the next day, and by another person if possible.
- The name of the company and the recipient, spelled correctly. A mistake here is particularly badly received.
- Consistent agreement (masculine/feminine, singular/plural), often broken when you recycle an old letter.
- The forgotten copy-paste, the infamous name of another company left in the text. This is the mistake that gets you eliminated on the spot.
Does the closing formula matter?
Yes, it closes the letter and leaves the last impression. In Switzerland, you stick to a sober, classic formula, such as "Je vous prie d'agréer, Madame, Monsieur, l'expression de mes salutations distinguées" (Indeed Switzerland).
Two mistakes to avoid at the end of the letter:
- The passive ending. "Awaiting the opportunity to meet you" or "I remain at your disposal" project a passive image. Prefer an active formula: "I would be delighted to present my motivation in person during an interview."
- Misplaced familiarity. A tone that is too casual jars in a rather formal Swiss context. You keep a professional register right to the end.
How do you avoid these mistakes without spending hours?
The method comes down to four habits: tailor each letter to the posting, replace every empty phrase with a fact, keep it to one page, and proofread with fresh eyes. Simple to say, longer to do when you are sending application after application.
That is exactly the role of candidat.app: from your background and the target job posting, the tool generates a cover letter tailored to each role, calibrated to Swiss codes, with no one-size-fits-all phrases or typos, and without inventing anything about your profile. You keep control of the text, and you save the time of writing and proofreading.
In short
The mistakes that sink a cover letter are well known and avoidable. The most serious remains the generic letter, sent with no personalisation. Next come the empty phrases with no proof, the overly rhetorical tone imported from France, the excessive length beyond one page, the spelling mistakes (the company name at the top of the list), and the passive ending. The common thread: the Swiss recruiter values restraint, precision and clarity. A short, targeted, error-free letter is worth a thousand impressive but empty formulas.
FAQ
Do you really need to write a different cover letter for each posting?
Yes. A generic letter is the most damaging mistake. You can keep a base structure, but the hook, the examples and the link with the company must be tailored to each role. That is what makes the difference on the first screen.
What length keeps you safe?
One A4 page maximum, that is the Swiss norm. Three or four well-built paragraphs are enough. A longer letter dilutes the message and risks not being read all the way through.
Is a single spelling mistake really a dealbreaker?
It can be, especially when several applications are equally strong. In French-speaking Switzerland, command of the language is a marker of seriousness. Proofread with fresh eyes, have someone else check it, and check the company and recipient names first.
How should you end a cover letter?
With a sober, classic closing formula, preceded by an active sentence rather than a passive one. Avoid "I remain at your disposal" and prefer a clear proposal to meet for an interview.
Is the cover letter still worth anything?
Yes. More than half of recruiters say it influences their decision. The CV is read very quickly; a good letter, short and targeted, is precisely the chance to hold attention and show your real motivation.
