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.

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.
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.
