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.

Question 1
Move zeroes in an array to the end while keeping non-zero element order, in place
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
