Thanks for elaborating! Was this part of the interview challenging? Seems to me like a surprise data structure coming up in an interview could be a bad thing (in terms of doing well). Edit: What have your other interview experiences been like? Similar to Google, or would different/more preparation be required? Also, what level are you at/interviewing for at these companies?
