Two rounds of interviews. They will ask you to introduce your research projects (mainly focusing on your CV), and may ask some following questions.
Overall, it is easy because it's all about yourself. No coding.
J'ai postulé en ligne. Le processus a pris 12 mois. J'ai passé un entretien chez Google (Toronto, ON) en sept. 2023
Entretien
It was two technical interviews, each one hour. It did not go well apparently although I answered almost all questions correctly. And they had used my very old CV when interviewing.
Had two research interviews and one chat with my host (whom I had contacted via email directly). The latter chat is considered a team matching interview, but for my case it was informal and not coordinated by recruiter.
