I applied through a recruiter. The process took 1 week. I interviewed at Meta (Palo Alto, CA) in Jun 2011
Interview
A Facebook HR recruiter contacts me directly through Facebook saying if I am interested in interview. The process consists of a phone interview and an onsite interview. Phone interview is asking my background and experience, while onsite interview is 30 minutes intense real coding question on white board. Two questions were given in the onsite interview. 1st one is reversing a linked list, and the 2nd one is writing a regular expression parser. However, since it only allowed 30 minutes to write actual codes for both questions, I wasn't able to finish them. (I finished 1 and 2nd one is half way) I then never got the reply from them.
Write the actual code to parse a regular expression including "*", which stands for 0 or more characters, "+", which stands for 1 or more characters, and ".", which stands for 1 exact character.
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.

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.
