I applied through other source. The process took 1 week. I interviewed at Meta (Palo Alto, CA) in May 2011
Interview
A FB HR person contacted me out of the blue directly. Everything was quick and well thought-through. It really looks like they interview tons of people a day and have an industrial interview process. After a brief HR phone chat, I was given a choice of a phone interview or a brief onsite - chose the latter.

Question 1
Given a set of non-overlapping integer ranges (1,3) (5,8), etc., and an input integer, what is the best way to organize the data and allow for quick search based on the input, etc.
The entire process usually takes 3–8 weeks, depending on scheduling and the specific role. Coding interviews heavily emphasize common DSA topics such as arrays, strings, trees, graphs, BFS/DFS, heaps, hash maps, and dynamic programming. System design becomes increasingly important for E4+ positions.

Question 1
Given an array of integers and a target value, return the indices of two numbers that add up to the target
Unexpectedly, the first question in the technical round felt familiar. It was about finding a subset of strings with unique character concatenation — same problem I had worked through on PracHub a few days earlier. The interview included a recruiter screen followed by a rigorous pair of technical interviews where I tackled data structures and algorithms alongside system design concepts. After successfully answering a few more challenging DSA questions, I received an offer. The entire experience was intense but ultimately rewarding, and I happily accepted the position.

Question 1
Given an array of strings, pick a subset whose concatenation contains no duplicate characters, and return the maximum possible length of that concatenation.
Standard cookie cutter interview with a coding interview, a system design interview and culture interview. The coding part is basically leetcode. The system design is what you can find on many youtube videos. The culture one is more tricky as they want to see that you fit Meta's culture, not that you were doing great at your existing company. So skills like dealing with conflict without calling in managers is sought after.

Question 1
coding: I forgot, sorry
system design: design ticketmaster
culture: talk about past project; when you disagreed with a peer; how I resolved dissagreements, etc.
