“Classic problem but I still fumbled the edge case where one interval completely swallows the next.”
“The problem statement itself takes a while to parse.”
“I started with the brute force and they let me finish it, then immediately asked what happens when N and Q are both a million.”
“I went straight to user pain points which felt right, but I spent way too long on the obvious stuff like wait times and button interfaces.”
“Got through it fine and had something close to the optimal approach ready for the follow-up too.”
“My first instinct was recursion but I pivoted to a stack approach mid-explanation which probably looked a bit shaky.”
“This question is a beast because it's really like six questions wrapped in one.”
“My first instinct was to frame it as a conflict to resolve, which felt wrong pretty fast.”
“I froze for a second because the question is so wide open it almost feels like a trick.”
“Classic fermi estimation.”
