I got an email from a recruiter at Facebook in January 2019, asking if I wanted to discuss an opportunity. The following week we had a recruiter screen. He told me that he had my resume from 2016 (three years prior!), when I applied to this job. It had been so long I hadn't even remembered applying! He asks when I would like to start the interview process, and I tell him that I'm comfortable starting at any time. The next Friday I received an email about the first round - an online coding challenge. The recruiter's email both said that I would be given 45 minutes to complete it AND later that I would be given 25 minutes to complete it, and to call him with any questions over the weekend I had to complete it. I both emailed and called to get this big time discrepancy clarified, and he did not respond until almost midnight Sunday night (it was due Monday afternoon). When he did respond (45 minutes), he extended the due date by 12 hours. His email also had a FAQ section about the question, which was very misleading. Without breaching the NDA I signed, I'll give you an analogy. The FAQ was all about baseball - there are 3 strikes before you're out, 4 balls to be walked, etc - so I expected and prepared for a "baseball" question. But then the question I got was about "football". Sure, I should know about it all, but it was so misleading that I thought I was given the wrong question! I honestly think he copy/pasted information about another question (that was for 25 minutes and about "baseball") into my email, causing all of these problems. Regardless of what the email says, prepare for any type of question in this round.

A typical Meta software engineer interview process: starts with a recruiter conversation, followed by two coding assessments, a system design session, managerial meeting, behavioral evaluation, and two LeetCode-medium coding interviews.
