You may assume, that we asked to reverse a binary tree on a whiteboard. Actually, the question about stack and queue was the only one from data structures area. So, I want to ask you: is this ok for a developer to google what stack is?
"is this ok for a developer to google what stack is?"
You are still missing it. What you have asserted you actually want is someone who groks both a stack and a queue--it doesn't matter if they forget which is which. Are you looking for someone who has memorized the definition of stack and queue? Or are you wanting someone who has internalized the difference?
I'm not contesting your assertion that it is knowledge you are looking for in an interview, the problem is your assertion that "there are some things you need to know off the top of your head". Knowing things off the top of your head vs having actually internalized what they are and how they work is the difference between watching someone play Dark Souls and having actually done it themselves. You are conflating vocabulary with understanding.
For further actions, you may consider blocking this person and/or reporting abuse
