The hiring process was quite smooth. You operate through a recruiter who acts as your aid. Mine was friendly and quick to respond to many of my questions, and kept me updated on the whole process.

The initial stage involved a brief phone meeting with the recruiter. She asked me a few straightforward questions, presumably to assess my competence, and then arranged a call with an engineer at Facebook.

On the call, we spoke for a while. The engineer explained the company culture, asked some "softball" questions about my resume, and then posed technical questions. I was asked to write code in a shared editor from my computer. These were basic CS-200 algorithms questions.

A few days later, I was invited to Facebook HQ and met with about half a dozen people, including my recruiter. She took me to lunch at the cafe, and then I proceeded through a number of interviews. Most of these involved coding questions that I had to write on a whiteboard, similar to the CS-200 algorithm style questions. One part of the interview that was enjoyable was a more architectural question, where I designed a system for serving a news feed.

A couple of days later, I received an offer over the phone from my recruiter. A full packet arrived in the mail a few days after that.

There was one coding question I had to answer that was particularly difficult. I was given a big chunk of Objective C code and asked to find the bugs in it.

It was a bit like "Where's Waldo" where there's more than one Waldo, but they don't tell you how many Waldos there really are.

I found a bunch of bugs but was nervous I didn't find them all.
