IOS Engineer Interview

IOS Engineer

I applied through a recruiter and the process took 1 week - interviewed at Facebook.

Interview Details – Recruiter contacted me through LinkedIn and asked for a CV. After a week or so, they contacted me back asking to answer general questions (regarding relocation possibilities, etc.) and four technical easy 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 a home-screen navigation or tab-bar navigation?
Understanding of platform: What is toll-free bridging?
After that, they've arranged a skype interview with Facebook engineer. The guy was iOS-developer and after briefly asking about my past experience, started with questions like follows:
-how will you describe iOS manual memory management for a new developer in few words?
-how would you implement call for canceling queued blocks with dispatch_after?
-Given a set of 2D points, some integer k, find the k points closest to the origin, (0,0).

Interview Question – -how would you implement call for canceling queued blocks with dispatch_after?   View Answer
