I applied online. The process took 2 weeks. I interviewed at INTERSECT (Paris)
Interview
I interviewed for a Product Owner role, they didn't ask for a case study. I had 3 rounds of interviews, first with HR, then with a senior Product Owner and a Tech Lead and finally with the Head of R&D and the CTO. They were nice people, serious about their job.
