I only had one question asked during fb phone screen :(
5 min introduction by both. Then 3 min question description and clarification. An LC medium, I gave a fairly straightforward solution in about 10 mins. Then spent 2 mins walking through (simulating) the solution per request. Then he started drilling very deeply about time and space complexity, spent 15 mins answering it and got tripped up a bit but corrected my self given hints. Then he says how can we optimize a bit more, which I tried to give an iterative answer that is same time complexity but avoids stack overflow obviously, didn't have time to finish it as we have only less than 10 mins left and he said ok he got my idea.
Is this bad?
