The process took 1 day. I interviewed at Meta (Palo Alto, CA) in Mar 2009
Interview
Phone interview was very professional and well structured. Covered a broad range of topics in computer science. Then I was called on site which consisted of many more rounds of interview with in-depth focus on algorithms and systems knowledge. There seemed to be a focus on an understanding of performance of systems.
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.
