Overview

APPI Intérim, a specialist in recruitment for aerospace, industry, and logistics, needed a more ergonomic and effective website to streamline connections between candidates and companies. We redesigned the digital experience by rethinking the UX/UI and developing a high-performance WordPress site aligned with the demands of modern recruitment. We structured the site to offer smooth, intuitive navigation. The goal: enable candidates to quickly find relevant job offers and recruiters to easily access key information. A redesign focused on user experience, readability, and simplicity of interaction. A site built to be fast, secure, and SEO-optimized, ensuring better visibility in search engines and a seamless experience across all devices. A tailor-made platform adapted to the needs of APPI Intérim and its ecosystem. With a modernized design and improved user experience, the site becomes a true tool serving recruitment, strengthening APPI Intérim’s employer brand.
