Meta Software Engineer interview questions

Online assessment initially, and then a series of final roudn onside interviews that consisted of 2 technical roudns and one additional behavioral round at the end, each lasting 45 minutes

Interviewing at Facebook was bit tough but not too crazy. Started with a quick recruiter call. Had virtual interviews mix of some coding, some system design. The questions do need some thinking but nothing out of left field. All the interviewers were chill and one even gave little nudges when I got stuck.
