I applied through an employee referral. The process took 3 weeks. I interviewed at Meta (Menlo Park, CA) in Aug 2013
Interview
I'm a Master student at a top CS grad school. I was doing an internship in Bay area in August and I started my process just two weeks before my last day there. Therefore the whole process was pretty fast because they (and I) want to finish all interviews before I leave so that I don't need to fly all the way from the east coast.
My friend helped me submit my resume. A few days later the recruiter contacted me via Email to schedule an initial HR interview. In this HR interview he told me great things about facebook and asked for my related experiences and why I would like to join facebook. He looks satisfied with my background and we moved forward to schedule a technical phone screen.
The phone screen went OK. I managed to code the first question in an efficient way but failed to figure out any possible way to solve its upgraded version with more constraints.
I received an email from the recruiter two days after the phone screen and was told I passed it. We scheduled an on-site interview in the same week.
The onsite interview consisted of three tech interviews. Two of them focused on pure coding/algorithm questions. One of them focused on behavioral questions and a easier coding question. I did well in one pure coding and the mixed one. I did OK in the last coding one: did not finish writing my code but the major part is clear and correct. I did make some minor mistakes and corrected them after the interviewer pointed it out.
Four days after my on-site interview, the recruiter asked me for two references. Two days later I received the offer.
Interview questions [1]
Question 1
All standard algorithm/data structure questions. Nothing about brain twists or programming language or computer/network related knowledges.
Took about a month from start to finish, which felt longer than I expected. After a couple of initial phone screenings, I faced a challenging technical round focused on system design. It was during this round that I was asked to describe overcoming a major career challenge. Interestingly, I had just reviewed a similar framework on PracHub, which helped me articulate my thoughts clearly. Overall, I appreciated the depth of the process and ended up accepting the offer.

Question 1
Describe Overcoming a Major Challenge in Your Career
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.
