I applied through a recruiter. The process took 2 months. I interviewed at Meta in Sep 2015
Interview
Phone screen test of duration 45 mins where interviewer started with briefly describing what he works on and straight away went to asking the interview question. Towards the end he left 5 minutes for me to ask questions.

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.
