The process took 2 months. I interviewed at Meta in Nov 2011
Interview
Contacted by a recruiter who asked about programming experience and why I want to work for Facebook. Then two separate technical phone interviews with software engineers followed. They introduced what they are working on in detail. They asked one or two typical coding questions, sharing them on the Collabedit.
Interview questions [2]
Question 1
Multiply two big integers which don't fit into an built-in integer type. How would you represent big numbers as a data structure? Write the function to multiply two big integers.
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
