I applied through other source. I interviewed at Meta
Interview
Facebook hires software engineers from all around the world. One can apply in their website . Sometimes they invite people for interview too. First phase is the phone interview phase. Normally 2-3 phone interviews take place, where the interviewee is asked to code in a shared document. Some other questions are also asked. If pleased from the performance, facebook will call the applicant for an onsite interview.
Interview questions [1]
Question 1
You are given an array of integers. Find all the combinations of the numbers of the array, that sum to another number(might be different for different combination) from the array.
One property of the array: The maximum number of the array will not be much greater than the others.
Took about a month from start to finish, which felt longer than I expected. After a couple of initial phone screenings, I faced a challenging technical round focused on system design. It was during this round that I was asked to describe overcoming a major career challenge. Interestingly, I had just reviewed a similar framework on PracHub, which helped me articulate my thoughts clearly. Overall, I appreciated the depth of the process and ended up accepting the offer.

Question 1
Describe Overcoming a Major Challenge in Your Career
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.
