Interview
I applied throw the Facebook career website. The process took about 2 weeks and consisted of a questionnaire, a phone call with the recruiter, and 45 minutes interview by phone (phone screen). All the process took place mostly by email. In addition, couple of days before the interview the recruiter invite me to an online video session with other applicants.

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.
