Two real QA screening questions. Scored like a candidate.

This Playwright test passes locally but fails about one run in five on CI. Diagnose why it is flaky and describe how you would rewrite it to be deterministic. You can answer in prose, pseudocode, or real code.

test('user can save a draft', async ({ page }) => {
  await page.goto('/editor')
  await page.fill('#title', 'Q3 regression plan')
  await page.click('button:nth-child(3)')
  await page.waitForTimeout(2000)
  const toast = await page.$('.toast-success')
  expect(await toast!.textContent()).toContain('Saved')
})
