Questions posées lors d’un entretien d’embauche pour Software Engineering Manager chez Meta

Went through Behavioral and System Design after recruiter call .It was not difficult but it didn't go through so guess i have to prepare more.Asked about typical Engineering management questions

I was contacted by a Meta recruiter by email. I then scheduled a call through the system instructed by the email. The recruiter called on the the day but 10 minute after the scheduled time. That's a quick call, and I was asked whether I would apply for position in infrastructure domain or product domain, I said 'product'. Then I was set up for a virtual interview with a Meta manager. At the beginning of the interview, I was asked whether I am OK to have someone else watch the interview, I said 'yes'. The interview was not hard, but unfortunately I didn't perform well.
