Meta Security Engineer interview questions

Recruiter screening, followed by technical screen (coding round + security domain), followed by an onsite loop with 4 interviewers. The 4 interviews were: interview 1: behavioral interview 2: coding interview 3: system design interview 4: Technical Hire/No-Hire decision received 1 week after onsite. Recruiters were VERY communicative and motivated to help candidates succeed. Best interview experience hands down

I was interviewed for phone screen. Got asked two questions . One is coding and other is conceptual. Interviewer was good. Quite fast to give the interview results. Do not bog down with one problem. Converse with interviewer.
