The French lettre de motivation is a formal letter first and a marketing document second, and its shape is taught in school. The applicant's address sits top left, the company's address top right slightly lower, the place and date top right ('Paris, le 16 septembre 2026'), then an 'Objet :' line that names the position, then the greeting. Skipping the address blocks in a PDF application still reads as incomplete.
The argument inside follows Vous–Je–Nous. Vous: what the company does and why this role exists — one short paragraph that proves you understood the advert and the business. Je: your evidence, the qualifications and results that answer it. Nous: what the combination produces, and the request for an entretien. This order is not a stylistic quirk; a letter that opens with Je inverts the courtesy the form is built on and is noticed.
The closing formula is the part non-French applicants get wrong most often. A formal paper letter ends with a full sentence of politeness — 'Je vous prie d'agréer, Madame, Monsieur, l'expression de mes salutations distinguées.' — and the greeting inside that formula must match the greeting at the top of the letter. An email application can shorten this to 'Cordialement,' or 'Bien cordialement,', and the trend in tech and start-ups is towards that shorter form.
