Process
A recruiter contacted me through LinkedIn and asked for my CV. After a week or so, they contacted me back asking me to answer general questions (regarding relocation possibilities, etc.) and four technical questions:
- Views: A square subview is centered when viewed in landscape. When the device is rotated to portrait, the square ends up closer to the top-right corner. What's wrong?
- Memory: What memory management policy do you use for an object's delegate? Why?
- UX: When would you use home-screen navigation or tab-bar navigation?
- Understanding of platform: What is toll-free bridging?
After that, they arranged a Skype interview with a Facebook engineer. The engineer was an iOS developer, and after briefly asking about my past experience, started with questions like the following:
- How would you describe iOS manual memory management for a new developer in a few words?
- How would you implement a call for canceling queued blocks with
dispatch_after? - Given a set of 2D points and an integer k, find the k points closest to the origin (0,0).

Great, if you don’t mind politics
iOS Engineer • Former Employee
Menlo Park, California, United States
September 10, 2023
Pros: A big tech company that still moves fast. You get to do lots of data science and analysis yourself on your own features to see if things are working or not. You have a suite of offices around the world to hang out from, even though I think now it’s mandatory three days at the office.
Cons: Building fbios takes about 20 minutes on a cold build, but it can be more or less. It's still not compatible with Buck 2.
Working with Objective-C++ is a nightmare, and the process to switch to Swift is long and low priority. It's definitely not as easy as it was for Android developers to automatically have their code switched to Kotlin.
Data analysis is messy if you don't set up the experiments perfectly. You end up presenting to people with incomplete data and having to come up with persuasive reasons for XYZ. It's all quite shaky and uncomfortable.
No matter what you do, some experiments you run will inevitably be unbalanced, and then you have to start over and wait another week.
