I applied through an employee referral. The process took 1 week. I interviewed at Meta (Seattle, WA) in Oct 2012
Interview
Five Interviews:
Talked about a past project and deep dived into my thinking about it.
Design a probabilistic english language word tokenizer.
Design a data processing infrastructure for petabytes of data and estimate the cost & perf characteristics of the system.
Permutate ways to count up to a number using a set of potential constituents.
How to efficiently choose numbers from a set and prove that the solution is the big-O optimal solution.
Interview questions [1]
Question 1
I was asked to mathematically prove the big-O bounds of an algorithm. I was a little rusty with my math, but my interviewer helped me and I got it.
The technical round hit me with a classic array manipulation problem: moving zeroes to the end without disrupting the order of non-zero elements. As I tackled it, I felt a wave of familiarity wash over me; I had just practiced a similar challenge on PracHub. The rest of the interview followed a straightforward path, with some easy behavioral questions sprinkled in. Overall, it felt very easy, but I wasn’t quite the right fit for what they needed, so I didn’t receive an offer.

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
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.
