The WTTJ profile is your prep material — read it end-to-end first
Every French scale-up on Welcome — Alma, Partoo, BlaBlaCar, Doctolib, Aircall — invests heavily in their WTTJ employer profile. Videos with founders and engineers, employee bios with personal interest sections, blog posts on culture and process. Block 20–30 minutes before applying: watch the founder video, read 2–3 employee stories, scan a recent article. Take notes of specific names, quotes, or projects mentioned. This is exactly what the recruiter will expect you to reference in your application — and it's what separates the candidates they remember from the ones they don't.
