Meta Content Designer interview questions

Exhausting process. First an interview with another content designer presenting my own case studies. Then a task to do at home. Then a presentation of my completed task and case studies to four people. Then three interviews about culture, collaboration and core skills. Difficult and very structured questions asked about collaboration but I was prepared. Culture interview was fine. Core skills interview was hardest. Interviewer was very cold and unfriendly. Gave me a flash task to do where I was asked how to improve 3 screens. When I was giving my input it was like talking to a brick wall and he didn’t engage with me. The recruiter told me the core skills interview would involve a deep dive into the task I presented but the interviewer only asked one brief question. I didn’t feel I got a chance to talk about my process or skills at all. I didn’t pass the core skills interview. The rest of the feedback was positive.
