The technical interview was very weak. There were almost no substantive questions about: standart libraries and frameworks (Foundation, UIKit, libobjc), working with UI, working with tables and collections (data source (prefetching), delegates), multithreading (XNU, POSIX, Inter-process communication, GCD, Operations), networking (URL Loading System, Alamofire), persisting data (Core Data, Realm, UserDefault, Security framework and keychain, Codable), multimedia (AVFoundation, Core Video, Core Image, MetalKit, MPS), CI/CD (Jenkins, GitLab Runners), design patterns, maybe some algorithms.p
