LinkedIn AI Engineer interview questions

The interview consisted of three main parts. First, There was an initial call mainly on the details of current status of the candidate. Second, there is an online interview with 2 LinkedIn employees on coding and machine learning questions. Finally, there is and on-site interview consisting of 4-5 sessions of at most 1 hour each (on coding, on machine learning, with a team lead/manager). In the end, I didn't get any return from the HR neither positive nor negative.
