Meta Product Designer interview questions

I went through 3 round of virtual interviews with varying teams. And a portfolio presentation with 2 case studies. Plus app review. And a dry run with the recruiter for my portfolio.

Recruiter reached out to me via email after an internal referral. I met a designer at Meta for 30 mins before my first interview. Screening: past work presentation and app critique. Onsite: 4 interviews – past work presentation, whiteboarding, app critique, background. Pros: - I got a lot of tips from the recruiter via email and general advice before the second interview. - I was able to reschedule very easily. Cons: - I could see the interviewers were doing something else during the presentation. Even though I said with accompanying slides: "When I first started at X company, there was only a logo and no design system. I initiated the project, assembled the team, etc." or "I was the sole product designer on this project", I got the same question over and over: "How much of this did you do?" When I was rejected, the recruiter mentioned: "it wasn't clear how much of it did you do". I was really surprised.
