After the background check, I was scheduled for a technical interview a week later. It was a phone interview requiring a section of video based questions. So have a windows machine for that. Yes, they want a Windows machine and nothing else, I asked them. So borrow one from your friend if you don't have one. She started with the questions immediately. Math, Programming concepts, C++, Signal processing and Matlab -> exactly one hour. Go through the basics and you should be more than fine. I struggled for some questions and gave abstract answers. Try not to give very detailed answers.

Une première interview simple par téléphone. La plupart des questions portées sur mes projets et les compétences que j'ai acquis durant mon cursus et des questions basiques sur mon CV comme les langages de programmation que je connaissais.
