I applied online. The process took 2 months. I interviewed at Meta (Palo Alto, CA) in Jul 2011
Interview
Phone screen, Excel test, phone interview, skype interviews, 30 page assignment, flew out for on-site interviews, more phone interviews, flew out again for on-site interviews.
They put me through the ringer before they hired me. But the questions were relevant and the people I met were great. This was back in their Palo Alto offices though.
Interview questions [1]
Question 1
Pre-IPO, they asked me to write a paper on the valuation of Facebook. They also asked me what I thought the greatest technological advancement was in the past 20 years.
Recruiter call was pretty standard, first round was 2 Meta tagged LC mediums in 45 minutes. On-site was 2 coding sessions of 2 LC mediums, a system design interview and a behavioral interview with an engineering manager.

Question 1
How do you answer if someone asks how long a deliverable or project will take?
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.
