First contact via recruiter then RH. The screening interview was scheduled. Important advice for interviewees: Avoid making questions about the problem statement and avoid and interact with the interviewer (it is not like a usual big tech interview). Leave the questions only for the end when it is given time to do so. Make sure you understand what was said by the interviewer but avoid asking again information that were already given. Trying to confirm will lead to comments saying they were already clear in the begining. They will not give you feedback if you are not approved unless you contact them. Despite all the nice propaganda about the company my impression is that there is a stressful environment.
