I applied through other source. The process took 2 weeks. I interviewed at Meta (Menlo Park, CA) in Mar 2012
Interview
A short initial phone chat with the recruiter (Who was excellent, even offering tips for the main interview) and then a technical phone interview with a developer.
The developer I spoke to was great, seemed like a nice guy and managed to pose some tough technical questions without seeming combative.
They got back to me within a couple of days to let me know they wouldn't be taking it further.
Interview questions [1]
Question 1
Worked through a few coding questions using a shared document, getting progressively more complicated and then went through a sort of thought exercise regarding the limits of the proposed solution in terms of constraints like bandwidth, CPU speed, memory and how performance could be improved without re-writing the basic algorithm.
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.
Standard cookie cutter interview with a coding interview, a system design interview and culture interview. The coding part is basically leetcode. The system design is what you can find on many youtube videos. The culture one is more tricky as they want to see that you fit Meta's culture, not that you were doing great at your existing company. So skills like dealing with conflict without calling in managers is sought after.

Question 1
coding: I forgot, sorry
system design: design ticketmaster
culture: talk about past project; when you disagreed with a peer; how I resolved dissagreements, etc.
The interview felt more straightforward than I anticipated for a well-known tech giant. After a recruiter screen, I faced a technical round that included a DSA question about finding the lowest common ancestor in a binary tree. I was pleasantly surprised when I realized the exact problem had popped up in the algorithm practice section on PracHub during my prep. Ultimately, the experience was decent, but I chose to decline the offer as it didn’t align with my current goals.

Question 1
Given a binary tree, find the lowest common ancestor of two given nodes in the tree.
