I applied through college or university. The process took 4 weeks. I interviewed at Meta (Ankara) in Oct 2011
Interview
I entered 3 phone interview , each takes about 45 minutes . Each time some engineer who works at facebook calls you via skype and wants you to open doc file , and first he starts talking about you, wants you to give information about your projects. After that he starts asking algorithm questions.

Question 1
Revert the given string and return the resulting string.
Ex: input: "face" , result: "ecaf"
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.
