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
I applied through a recruiter. The process took 1 week. I interviewed at Meta in Sep 2014
Interview
I was contacted from a recruiter through Linkedin. I reply with my updated resume and the times for a phone call. The recruiter call me back the same week and ask about general background and some JavaScript questions, maybe because I commented about wanted to work in UI. The call took about 30 min. Two days later I received an email with a code challenge. After I delivered the challenge, two days later I got an email about not moving forward in my interview process.
In general the recruiter was super helpful with all the questions that I had.
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.
