The process took 4 weeks. I interviewed at Meta (Menlo Park, CA) in May 2016
Interview
I had one phone interview + 4 on-site interviews: 2 coding, 1 cultural + coding, 1 system design.
My experience suggests that I should have not waste my time with Facebook. It seems that they just interview with people without giving them offer. I had a perfect day at my on-site interview. I heard a few others were like me as well. None of us got an offer. In my case, two of the interviewers were really surprised with my answers and I finished 15 minutes before the time goes up and we chat the rest of the time. One of the interviewers told me that she believes Facebook should hire less people to have enough challenges for the current employees. Recruiters at Facebook are also terrible. They respond to your emails with template answers and unfortunately have very low technical knowledge.
Took about a month altogether, which felt longer given the intensity of the process. Kicked off with a technical screening, followed by two rigorous coding interviews. The DSA question on binary tree vertical order traversal hit me hard at first, but then I recognized the prompt instantly — I had just worked through something similar on PracHub. The final round was focused on system design, and while I ended up receiving an offer, I ultimately declined it. Overall, a challenging experience that definitely sharpened my skills.
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.
