“This is the kind of question where you can go wide or deep and it's genuinely hard to know which they want.”
“I went straight to 'I'd escalate to my manager' and the interviewer just kind of waited, so I kept talking and dug myself into a weird hole about company policy.”
“I knew it was a level-order traversal thing pretty quickly, but I wasted maybe two minutes half-explaining DFS before catching myself.”
“I went straight for a top-down approach and started throwing out population numbers, which felt okay at first.”
“I went with a tokenizer feeding into a recursive descent parser which felt right and the interviewer seemed fine with the direction.”
“This one pulled me in two directions at once.”
“This one sprawled in every direction.”
