I was very nervous at first about what I would be asked, seeing as I hadn't interviewed in the past three years. I applied through a recruiter who then helped me schedule a Skype call with an engineer at Square. I was afraid of the questions I would be asked because I had read that the interview was very difficult.
When presented with the question, I was surprised because I was capable of solving it. There was a 45-minute time limit, and you were allotted 15 minutes at the end for questions. I was capable of solving the question but took too long doing so, and for this reason, I failed.
By the way, I am a decent programmer, and I think the question asked was very fair. Just make sure you practice many problems so that you are quick on your toes when coding the solution.
The question was very fair.
