Interview process was in 3 steps, initial interview with recruiter, then hiring manager, then panel of 5 interviewers and 5 interviews. (not counting the writing assessment or aptitude assessment) First two steps are quite straight forward, description of personnel profile and job requirements. With the hiring manager, questions will be based on Amazon principle (1 in my case). The final step is more challenging. All 5 interviewers are going to discuss one leadership principle. In my case, all were focused on one or two principles. It is good to be prepared, and have different examples (STAR). For the bar raiser, be prepared to dive deep into the example.
