I applied through an employee referral. The process took 1 week. I interviewed at Meta (Tel Aviv) in Apr 2015
Interview
First interview was HR phone interview, with 3 simple technical questions.
Second interview was technical over the phone with one of the employees. the interview was on shared online whiteboard.
overall process was very good, people are very nice and helpful.
during the interview, the interviewer gives you tips and directions, always focus about what you are doing.
Interview questions [1]
Question 1
HR: hash function search time, what is O(n)
Programming: write a function that get an int array, each int has category which can receive by a given function. category is one of (0,1,2).
eg Array[1]=20, get_category(20)=1
sort the int array by the int category.
following question, sort without addition array\space
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.
