Me postulé a través de un reclutador. El proceso tomó 4 semanas. Acudí a una entrevista en Meta (Menlo Park, CA) en jul 2014
Entrevista
I was hiring specifically for an iOS position. The recruiters start with Obj-C 5 multiple choice questions, which required some surprising depth. I won't get into specifics, but take time to understand memory management (even with arc), blocks, addresses and pointers.
After was a phone interview which mostly involved a collaborative coding question. The questions asked here were very typical algorithmic questions, the answers usually involved a hash to cache meta values to increase performance.
Protip: Be familiar with NSSet and NSOrderedSet. These data structures are more performant than NSArrays for some operations, and I found myself using them in almost every answer.
Then you have an onsite visit, with 4 additional interviews: 2 coding, 1 design, and 1 "culture fit" which, for me, was really another coding interview.
Your recruiter will contact during the next week or two afterwards to give you updates on your status. I believe there are three different meetings where your interviewing notes are reviewed and given consideration.

Pregunta 1
What is something other people misunderstand about you?
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.

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.

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.

Given an array of strings, pick a subset whose concatenation contains no duplicate characters, and return the maximum possible length of that concatenation.
