Algo
The coding round, for the roles that get one. 4 algorithmic problems with market flavoured statements, 70 minutes, and your solutions run against hidden test cases exactly as an auto grader would.
Algo
4 algorithmic problems in 70 minutes, in JavaScript. Write a function called solve, run it against the sample cases as often as you like, then submit to run it against the hidden ones. Scored out of 600 in proportion to the cases you pass.
How your code runs
In a sandboxed worker inside your own browser. Nothing is uploaded, nothing runs on our server, and an endless loop is stopped by killing the sandbox rather than hanging the page. That is also why this drill is not ranked: a score we cannot verify has no business on a leaderboard.
Where your code runs
In a sandboxed worker inside your own browser, and nowhere else. Nothing is uploaded and nothing is executed on our server. A loop that never ends is stopped by killing the sandbox, so the page cannot hang.
Why this one is not ranked
Every other ranked game here has its score recomputed on the server from problems the server issued. That is impossible for arbitrary code the server never sees, so rather than put a leaderboard on top of an honour system, this drill has no leaderboard at all. Score out of 600, and the bar these rounds are reported to set is around 500.
What we are not claiming
Reported lengths for the real rounds vary a lot by role: three to four problems in anywhere from seventy to a hundred and fifty minutes, at LeetCode medium to hard. Seventy minutes here is a choice, not a claim. The problems are written by simplytk and are not anyone else's questions. Real rounds also let you pick your language; this one is JavaScript only, because that is what a browser can run safely.
