1056 ready-made tests across 264 skills. Every question comes from Winkle’s shared question bank, and only questions that have been reviewed and approved are used.
Junior draws on introductory questions, Mid draws on intermediate questions, Senior draws on advanced questions and Staff draws on expert questions. A level only appears for a skill once the bank holds at least 4 approved questions at that difficulty, which is why not every skill has every level yet.
Paste the job description and Winkle drafts a test for that exact role, with coding questions where the role needs them. You review every question before it goes out.
Yes. Using a test puts a draft in your account, and you can edit, remove or swap any question before it goes to anyone.
Yes, by default, at the duration shown on each test. Switch timing off in a test’s settings and the duration becomes a suggestion instead of a limit.
New tests start with camera, screen and microphone recording on, every time the candidate leaves the test tab logged, copy and paste blocked outside the code editor and questions hidden while the window isn’t in front, and printing blocked. Each is a switch in the test’s settings. You can also set how many times a candidate may leave the tab before the test submits itself, and shuffle the question order and answer options for each candidate.
