Initial screening over Skype (5 multiple-choice questions) by a recruitment officer.

Two Skype interviews, writing code in Coderpad.

Onsite interview consisted of four more sessions:

• Mostly writing code on a whiteboard.
• One "culture fit" interview.
• One design interview.

Everyone was friendly and knowledgeable. The entire process was stress-free and actually a bit of fun.

I wrote a lot of code during these interviews, doing two or three exercises per interview. If I had to do it over, I would code more slowly to avoid having to do so many.

Given nested arrays, write an enumerator class such that next() returns the elements in sequential order. For example:

[1,[4,3],6,[5,[1,0]]] -> 1, 4, 3, 6, 5, 1, 0

Also, implement allObjects for this class.
