The first stage involved two phone interviews with coding using collaborative software like CollabEdit.

A couple of days later, an on-site interview was offered.

I was given the option to fly out to Menlo Park the very next day or interview over Skype. I chose the latter due to time constraints.

The first interviewer (second stage), after going over my experience, asked me to design a simple web-based editor (like CollabEdit). Questions about basic tree manipulation followed, as the DOM was represented as a tree.

This interview ran long, hence I was late to the second one.

I was asked to quickly implement a solution to the N-Queens problem for the second interview. I couldn't finish answering before time ran out.

Provide a solution to the N-queens problem.
