I applied through an employee referral. The process took 4 weeks. I interviewed at Meta (Menlo Park, CA) in May 2012
Interview
I was contacted by recruiter via employee referral. Chose to go on site for initial interview. This was followed by onsite day of interviews a few weeks afterwards (I asked for some time to prepare for coding tests). The second set of interviews comprised of 2 coding tests, one design, one behavioral, lunch with hiring manager and one interview related to my technical specialization. Received offer within a week of final set of interviews.

Question 1
Coding tests were the hardest part for me since I have been out of school for a long time now :) Prepare for questions related to trees, graphs, strings, dynamic programming and practice writing code on paper.
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.
