I interviewed for product design around Q3 2022. I passed the interview process, but a hiring freeze took place and I didn't get an offer. Despite having had that experience, I can honestly say that Meta has one of the best interview processes I've ever seen. Their steps are very clear, they provide you with great helpful prep materials, and their recruiters are experts and talented.
The recruiter is very supportive. First round is a deck presentation. Second round is full loop: deck+ BQ+ whiteboard+ app critique. The Overall experience is good, it takes around a whole month
Straightforward like any big tech interview, but long and intense. Formats are pretty standardized so it just takes practice. Questions appear like it's from a bank, so if you're prepared you should be fine.

Interview
I was reached out by a recruiter. Started with the recruiter call, then portfolio presentation, then full loop (Portfolio presentation - app critique - design challenge - background). They had very strong emphasis on design craft and visual excellence. Recruiter who helped me prep was very nice and helpful.
