I was contacted by a recruiter through LinkedIn.

I told them I'm not currently looking for a job, but since Facebook seemed like a great opportunity, I agreed to interview.

The interview presented a rather easy question, but I had trouble quickly writing code on the whiteboard – something I've hardly ever done in my programming career.

I also don't have much interview experience in the US, which I did warn them about.

Despite this, I later received a reply stating that I failed due to "coding performance." Whatever that means.

It felt as if they were looking for professional interviewees rather than computer programmers.

The whole process felt like a waste of time.

A trivial question on breadth-first graph traversal.
