> If you're considering searching for a solution and cutting and pasting it as your answer, know that leetcode has basic tools to detect this. They track your time and keystrokes.

"Fun" story: years ago, I was interviewing for some position at a now-defunct startup that was then a darling of the SF tech scene. Several people worked there who had worked with me, as an engineer, at a prior company. It would have been trivial to verify my engineering ability by asking their existing employees.

Instead, as a screening interview I was given an at-home, timed, leetcode-style test in a UI with an abysmally bad web-based code editor. I quickly noped out of the terrible thing, opened emacs, coded the solution, and pasted it into the editor window. I submitted, the code passed whatever tests, and I was assured a response.

The next day I was summarily rejected, with only a vague comment about "lacking technical ability".
