I applied through an employee referral. The process took 2 weeks. I interviewed at Meta in Mar 2015
Interview
The hiring cycle is pretty fast. I got the email from recruiter and it took only one day to setup the interview the 1st round interview. After I finished 1st round I emailed the HR for updates and HR get me the result the following day with an arrangement for 2nd round phone interview. And it took about 2 days after 2nd round to know the results. The whole process is less than 2 week, pretty sweet :)
Interview questions [1]
Question 1
Around the medium level algorithm questions. The only one I remember is to print all paths from root to leaf of a tree, using both recursive and iterative methods. 2 question for 1st round and 3 questions for 2nd round.
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.
