“Pretty open-ended.”
“The median-of-a-stream part I knew cold, two heaps, keep them balanced, done.”
“I knew it was a DP or stack problem the second I read it, but the efficiency rating layer threw me off.”
“The question itself sounds manageable until the follow-ups start and you realize they want the full autopsy, not the highlight reel.”
“I knew the broad strokes but fumbled the specifics under pressure.”
“Two-pass approach, count all characters first then scan again for the first one with a count of exactly one.”
“This question has way more parts than it looks like at first.”
“I pulled from production support work, talked through a workflow failure I investigated by digging into logs and comparing successful runs against broken ones.”
“I went with a story about a project getting scoped down last minute and how I had to adjust.”
“This one tripped me up more than I expected.”
