I applied through an employee referral. The process took 2 weeks. I interviewed at Meta in Nov 2015
Interview
Phone interview.
The HR arranged an phone interview after my application was referred by an current employee.
The interviewer called on time. He introduced himself very quickly and also talked about what he is doing now for the job. After that he let me to talk about the most challenge project I have ever made. Then the coding question begins: he tried to mislead me by using a very long description about the question. For example, this is about PHP bla bla... But actually the question is about Depth First Search. There was just one question because I was slow. I think I will be rejected.
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.
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.

I applied online. I interviewed at Meta (Menlo Park, CA)

It's honestly striaght from leetcode tagged
There are no surprises if you do tagged you would be good and do well.
System design is much harder. Would recommend using hello interview.
