I applied and received a multiple-choice quiz on Objective-C and Swift. The questions seemed fair; however, you are given only about 20 minutes to answer 14 questions.

A fair amount of these questions contain code, mostly Objective-C. I'm not sure how one is supposed to adequately answer all the questions, as well as read and comprehend the wordy questions, in the time allotted. I ended up getting bogged down trying to follow code line by line and couldn't complete the last question.

General rule of thumb: If you have a multiple-choice word problem with code, then give at least 2 minutes for each question.

I have worked for many large tech companies in and around Asia. Please understand that many senior engineers aren't going around answering multiple-choice questions all day. It is understandable that these individuals should be given more time to answer what you want to ask them.

As I said before, the questions are fair, just not enough time to answer them in a satisfactory way. Then again, that could be HackerRank's (the company they outsourced this to) approach.

I wasn't prepared to be asked as many Objective-C questions as I was. I thought that most people would have moved to Swift by now. At least, every company that I've worked for in the past six years has.
