    Multiple choice marks itself. Written answers get a score with the reasoning behind it, so a surprising number can be checked.

About the PHP test.

What employers ask before sending the Senior PHP test, answered with its real figures.

  • How long does the Senior PHP test take?

    20 questions in about 60 minutes. The clock is set to 60 minutes by default. Switch timing off in the test’s settings and the duration becomes a suggestion instead of a limit.

  • What kinds of questions are in it?

    It mixes multiple choice and debugging questions. Coding questions are answered in a code editor in the browser. Its questions run from intro to expert difficulty.

  • How is it scored?

    Automatically. Multiple choice marks itself the moment the candidate submits. Written answers are scored against a model answer, with partial credit for an answer that is partly right, and every written score comes with the reasoning behind it so a surprising one can be checked.

  • Which PHP level should I send?

    PHP comes at 4 levels: Junior (20 questions, 45 min), Mid (20 questions, 60 min), Senior (20 questions, 60 min) and Staff (20 questions, 35 min). Junior draws on introductory questions, Mid draws on intermediate questions, Senior draws on advanced questions and Staff draws on expert questions. Pick the level the role needs, not the one on the candidate’s CV.

  • Can I change the questions?

    Yes. Using a test puts a draft in your account, and you can edit, remove or swap any question before it goes to anyone.

  • How do you keep every result fair and honest?

    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.

  • Why can’t I see the questions on this page?

    A public page with the questions on it is an answer key for every candidate who finds it. Sign up free and using the test puts every question in front of you to review before anything is sent.

  • What does it cost?

    Nothing to start: sign up free, with no card. The plans and their limits are on the pricing page.
