I applied online. The process took 1+ week. I interviewed at Meta (Seattle, WA) in Aug 2011
Interview
I got a phone call from a recruiter one day after I applied online. She asked me general questions about my experience and expectations. Onsite interview happened about 10 days later. I only talked to one guy, he once again asked me about my experience, about what I like about FB. Then he asked me one coding questions: given is a binary tree, write a function that returns Lowest Common Ancestor of two given nodes. After I did that, there was some time when I was allowed to ask some qustions about the company/team/ etc. Next day I received an email saying they have no position for me.

Question 1
what can FB do to beat its competitors in my country, where it is not the most popular social network.
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.
