Really horrible/bad experience. I had two technical rounds. After the first round, HR asked me to wait for the next round, which happened post-lunch. The interviewer came and asked about my experience, then started asking basic questions. Finally, he asked one more final on-boarding question and explained something. In the middle, another person came. He explained it in a different way and with a different concept. Finally, both agreed with the second interview point. Both asked me to do this and sit back; they would come and review. Somehow, I completed it and waited for 20 minutes. Suddenly, HR came and said, 'Sorry, I forgot to inform you that you can leave for the day, and we will get back to you.'

I don't think this is the way to treat professionals. If you guys are not interested, why are you calling people for interviews?

How will you move an item from an array of objects from one index position to another?

As usual, UI questions:

1. Closures: When and where do we use them?
2. Design patterns in your career.
3. Vertically align a div with and without transform.
4. Currying.
5. Scope.
6. Hoisting.
7. call, apply, bind.
8. How to check the type of a variable (primitive and array).
9. Native code of isArray.
