I felt that asking the looksay question is the wrong caliber for a front-end developer. I had some difficulty with it because I have never heard of this question/algorithym before (I googled it later). It felt like the interviewer was looking for one specific answer and I could tell that he was getting frustrated that I didn't know the answer. He quickly ended the interview. To me it seems like this is not the type of question to be asking if they are looking for a front-end developer. Seems like a good question for a senior DB role.
