> I had to look this data structure up. Granted, once I reviewed it, node insertion is trivial, but I hope you gave applicants that opportunity. We couldn’t - there was no Google at the time of our IPO. (More importantly there was no mobile Internet). But the reaction “please clarify what are you talking about” is absolutely sapient, so you would have passed. But note that this: > node insertion is trivial - is much less sapient. In my alma mater “trivial” meant that you are able without a pause to write down a proof - without a single error. And this particular task is not designed to be rushed through, there are a couple of potholes. Anyway, hire / no hire was not based upon the absolute correctness of the code. It was mainly based upon the applicant’s reaction to me pointing some “obvious” error in their code. We were not looking for A+ students, we were looking for the people we can work with.
