I applied through a recruiter. The process took 1 week. I interviewed at Meta (Menlo Park, CA) in Oct 2013
Interview
It was 4 interviews in total with a lunch break in the middle.
Two interviews are considered to be conding, one disign and one cultural with a little bit coding.
Overal algorithmic problems on the interview were pretty simple.
But they pay attention to implementation details, make sure that code actually works properly for all the cases and try different test cases.
FB provides great hotel accomodation, one of the best hotels I've ever been :)
Interview questions [1]
Question 1
Gray code, it was lack of time on a cultural interview. I think something like 15 minutes or so it was quite challenging.
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.
