More Live-Round Problems
HubSpot's onsite has one live coding round, with one practical problem in about an hour, usually easy to lower-medium. The Live Coding Round covers how that hour runs and works through three of its problems. Here are three more.
The first is a merge that candidates have named more than any other live problem for about ten years. Some candidates got the second in the same hour as the first. The third is a graph problem dressed up as a messaging question.
None of the three needs a rare data structure. Candidates call the first one easy, yet some still hear no after a working solution, and the feedback tends to mention edge cases raised late and missing tests. So list the cases before you type, like an empty input or a limit larger than the input. Then write a few tests of your own before anyone asks.
