I applied through a recruiter. The process took 1 week. I interviewed at Meta (Palo Alto, CA) in Oct 2010
Interview
I had on campus interviews in the spring and then decided to interview for full time in the fall. I had three interviews - the first went very well, the second was terrible, the third was alright. The terrible interviewer asked some basic technical questions involving writing code on the board. As I thought out loud, I asked the interviewer clarification questions and then ultimately asked whether I should start writing code on the board. The interviewer either did not respond to my questions or mumbled off a few incomprehensible words. I started writing code and as soon as I stepped back from the board, the interviewer pointed out my mistake without giving me a chance to assess the code myself. He did this an another two times for the subsequent questions.
Overall, the questions were not difficult at all. It seems that Facebook wants to make sure that you code frequently enough that you do not make any errors on your first hack at a problem. This seems to fit the "go fast and break things" motto. Although things didn't work out for me, I got an offer from Google, so I guess that's not a bad second choice.
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)
Interview
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.
