During technical interview I was asked about Swift & iOS: generics, generic protocols, how Swift Optionals work, difference between closures and functions, how memory is allocated for closures, capturing values in closures, difference between structs and classes, how memory is allocated for structs and classes + edge cases (struct in heap, class in stack). After that showed me different code samples and tasks: DispatchQueue spaghetti task (to determine execution order), execution order, Unit-Testing sample task (to improve code and make a proper test), retain cycle task (to find this cycle or prove that there's no problems)
