Meta Data Scientist interview questions

The first interview was an HR call that asked personal questions and work experience, after that they sent a Word file with additional interview questions and analytical questions. Some of the questions were: 1. What course projects and/or experience have you gained experience in Data Analysis 2. How does a Data Science role at Facebook align with your background, skills and areas of interest? 3. Let’s say we want to figure out for any Facebook (or Instagram) user, who their best friend is so we can prioritize showing their content in the News Feed. What product signals and metrics (please max at 5) would you use to determine who a user’s best friend is? After that there is a technical interview which included a analytics question and two SQL questions. Finally there is a personal interview and probability questions.
