applied online. Contected by recruiter for initial screening in facebook office. When to local fb office, where I waited for few minutes after getting to reception. First, recruiter gave tour of center and talked about perks and then took me to conference room, where I met interviewer whole first discussed about my past projects and then jumped on coding question.
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.
