A person from the hiring team called me last week about this position and asked me that after shortlisting, I would get a call. But four days passed, and no call was received from them. So, I found a post from Lowe's on a job portal and applied on Saturday. I received a call on January 23rd, 2017. After knowing that I was serving my notice period, the HR person arranged a call in the evening. So, you can understand how cooperative they are. The HR guy was very nice and asked me to read about Swift, as they would only ask me about Swift.

1. What are closures in Swift?
2. What is the use of defer in Swift?
3. What are design patterns in iOS?
4. Have you worked on Apple Watch? Do you know how to create apps for Apple Watch?
5. What data structure does Google use to search data?
6. Do you know how Apple Watch interacts with iPhone to make a call?
7. Create a class for Bookshelf and search how many books can fit in empty space.
