I applied through other source. The process took 1 week. I interviewed at Meta (Palo Alto, CA) in May 2011
Interview
A FB HR person contacted me out of the blue directly. Everything was quick and well thought-through. It really looks like they interview tons of people a day and have an industrial interview process. After a brief HR phone chat, I was given a choice of a phone interview or a brief onsite - chose the latter.

Question 1

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.
