# Device and Browser Compatibility

> Which test types work on mobile, which need a desktop, and which browsers to use for the smoothest experience.

<Tip>
  Quizzes, psychometric tests, English communication tests, and video responses all work on phones. Programming, SQL, CSS, Excel, and typing tests need a desktop or laptop. Whatever the device, **Google Chrome** is the recommended browser.
</Tip>

## Mobile-Friendly Test Types

Equip supports many **test types**, and several of them work well on a phone or tablet. The table below shows which tests candidates can attempt on mobile.

| Test Type                         | Works on Mobile? |
| --------------------------------- | ---------------- |
| Quiz (MCQs, essay-type questions) | Yes              |
| Psychometric Test                 | Yes              |
| English Communication (CEFR)      | Yes              |
| Video Response                    | Yes              |
| Programming Challenge             | No               |
| SQL Challenge                     | No               |
| CSS Challenge                     | No               |
| Excel Test                        | No               |
| Typing Test                       | No               |

<Note>
  Even when a test works on mobile, recruiters can require a computer for any test by turning on the **Enforce Desktop** proctoring setting. If it is enabled, the test will not load on phones or tablets. See [Proctoring Settings](/proctoring-settings).
</Note>

## Desktop-Only Test Types

**Programming**, **SQL**, **CSS**, **Excel**, and **Typing** tests run in interactive environments, such as a code editor or a simulated spreadsheet, that need a full-size screen and keyboard. These tests can only be attempted on a desktop or laptop.

Desktop-only tests carry a **Desktop Only** badge, so candidates know up front which device to use. For these test types, the Enforce Desktop setting is on by default.

<Warning>
  If your assessment includes even one desktop-only test, ask candidates to attempt the entire assessment on a computer. Switching devices mid-way is possible, but starting on the right device avoids interruptions.
</Warning>

## Recommended Browsers

**Google Chrome** is the recommended browser for all Equip assessments and AI interviews. Some proctoring features depend on browser support, so the browser a candidate picks can matter.

| Feature                               | Browser Support                              |
| ------------------------------------- | -------------------------------------------- |
| Assessments and proctoring in general | Chrome recommended                           |
| Switched Tab Screenshot               | Chrome, Edge, Safari, and Firefox on desktop |
| Multiple-monitor detection            | Chromium-based browsers only (Chrome, Edge)  |
| Video interviews on iPhone or iPad    | Safari required                              |

Before any test begins, Equip's setup screen walks candidates through granting camera and microphone access, with built-in buttons to test both devices.

<Tip>
  Candidates can verify their device works by attempting the free **demo tests** shown before the assessment. The demo checks the exact test types in the assessment, so a working demo means the real test will load too. See [Demo Tests](/demo-tests).
</Tip>

## Troubleshooting Device Issues

If a test will not load or the camera and microphone are not detected, work through this ladder in order. Most pre-start issues are resolved on the device itself.

<Steps>
  <Step title="Check the webcam and microphone">
    Confirm the camera and mic work in other apps, and that the browser has permission to use them. Equip's setup screen includes test buttons for both.
  </Step>

  <Step title="Try an incognito or private window">
    Extensions and cached settings can block camera or screen access. An incognito window rules them out.
  </Step>

  <Step title="Switch browsers">
    Try Chrome first. If Chrome is unavailable, try Safari or Edge, and use Firefox only as a last resort.
  </Step>

  <Step title="Switch devices">
    If nothing works, open the same assessment link on a different computer. An unfinished attempt resumes on the new device. See [Resume Your Attempt](/resume-your-attempt) for how timers behave when resuming.
  </Step>
</Steps>

<Note>
  A candidate who has not yet seen any questions can safely click their assessment link again on any device. For issues that appear after questions have loaded, see [Candidate Issues](/candidate-issues).
