I applied through an employee referral. The process took 2 weeks. I interviewed at Meta
Interview
Referred by school mate and got the phone interview. Failed in the first round interview. No questions on resume. Just two coding questions. First one is easy. I just said minHeap solution, then the recruiter directly said next. I was stuck at the second problem and that is the reason why I failed.

Question 1
1. Given 1 billion numbers, find 100 largest numbers
2. Prefix notation +*123 = 5
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.
