I applied through a recruiter. I interviewed at Meta (Seattle, WA)
Interview
I only did the first technical screening with a developer and this involved 2 technical problems, in my opinion they were easy type problems. One involved merging two arrays and the last one a tree type questions. Nothing hard really, but at the time I was a bit confused on how to optimized things. Regardless, the interviewer was very nice and gave good hints in order for me to complete both problems in time.

Merge two sorted arrays but make sure there are only unique numbers in your result.
1 leetcode med, 1 leetcode hard. make sure you know your DSA and leetcode questions. I wasn't able to get an offer bc i didnt complete the second question. Got a reply 2 days later saying they would move on
Overall, the process took a little over two weeks, which felt a bit longer than I anticipated. After a quick screening, I went through two technical rounds focusing on coding and DSA concepts. One of the questions was a classic palindrome check; mid-way through, I realized it was something I had practiced on PracHub just days earlier. The final step was a casual behavioral interview. I was relieved to get an offer shortly after, which I happily accepted.
