Why a Weak Playwright Answer Doesn't Always Mean Rejection

INTERVIEWER NOTES (example format)

Fundamentals (locators, waits, assertions):   4 / 5
  - strong on getByRole and web-first assertions
  - unsure on iframes (frameLocator)

Reasoning:                                     4 / 5
  - talked through popup handling from first principles

Honesty:                                       5 / 5
  - said 'I have not done this, here is my guess'

Learning:                                      5 / 5
  - used the hint on waitForEvent and wrote it correctly

Overall: proceed to next round

INTERVIEWER NOTES (example format)

Fundamentals:   3 / 5
  - unsure on iframes

Reasoning:      2 / 5
  - jumped straight to an answer without thinking

Honesty:        1 / 5
  - claimed page.switchToFrame() exists in Playwright
  - insisted after I said it does not

Learning:       2 / 5
  - ignored the hint

Overall: do not proceed

The original miss was identical. The reaction was not.

import { test, expect } from '@playwright/test';

test('pay inside an iframe', async ({ page }) => {
  await page.goto('/checkout');
  const payment = page.frameLocator('iframe[title="Payment"]');
  await payment.getByLabel('Card number').fill('4111111111111111');
  await payment.getByRole('button', { name: 'Pay' }).click();
  await expect(page.getByText('Payment received')).toBeVisible();
});

test('help opens in a new tab', async ({ page }) => {
  await page.goto('/dashboard');
  const popupPromise = page.waitForEvent('popup');
  await page.getByRole('link', { name: 'Help centre' }).click();
  const help = await popupPromise;
  await help.waitForLoadState();
  await expect(help).toHaveTitle(/Help/);
});

import { test, expect } from '@playwright/test';
import path from 'path';

test('upload a resume', async ({ page }) => {
  await page.goto('/profile');
  await page.getByLabel('Upload resume')
    .setInputFiles(path.join(__dirname, 'files', 'resume.pdf'));
  await expect(page.getByText('resume.pdf')).toBeVisible();
});

test('confirm before deleting', async ({ page }) => {
  await page.goto('/projects');
  page.once('dialog', async dialog => {
    expect(dialog.message()).toContain('Delete this project?');
    await dialog.accept();
  });
  await page.getByRole('button', { name: 'Delete' }).click();
  await expect(page.getByText('Project deleted')).toBeVisible();
});

Interviewer: How would you click a link that opens in a new tab?

Candidate: Honestly I have not done that in Playwright yet.
Let me think. A new tab is a new Page object, so I need to
catch it when it appears. I would expect an event for that.
Is there something like waiting for a popup event?

Interviewer: Yes, page.waitForEvent('popup').

Candidate: Then I would start that wait before clicking,
so I do not miss the event. Click the link, await the
promise to get the new page, wait for its load state,
and assert on its title or URL.

Subject: Thank you - QA Automation interview

Hi [Interviewer name],

Thank you for today's conversation. I enjoyed the
Playwright discussion. After the interview I practised
handling iframes with frameLocator and wrote a small test
for it in my practice project.

I am still very interested in the role and happy to
share the code if useful.

Regards,
[Your name]

MISS LOG (fill within an hour of the interview)

Question asked:               __________________________
What I said:                  __________________________
What the right answer is:     __________________________
Kind of miss: edge API / less common / core / bluff
Did I recover? How?           __________________________
Practice task to fix it:      __________________________
Done by (date):               __________

Rule: every 'core' miss gets a practice test written
before your next interview.

EDGE TOPIC DRILL (one evening)

Write one passing test for each:
[ ] fill a field inside an iframe with frameLocator
[ ] catch a popup with waitForEvent('popup')
[ ] upload a file with setInputFiles
[ ] accept a confirm dialog with page.once('dialog')
[ ] download a file:
    const dl = page.waitForEvent('download');
    await page.getByRole('button', { name: 'Export' }).click();
    const file = await dl;
    await file.saveAs('exports/' + file.suggestedFilename());

Then explain each one aloud in 30 seconds.

PHRASES THAT HELP AFTER A MISS

"I have not used that directly, but I would expect ..."
"Let me reason from what I know about Playwright events."
"Is that the direction you were thinking of?"
"Thanks, so with that method I would ..."
"I would confirm the exact signature in the docs."

PHRASES THAT HURT

"I am sure it is page.switchTo()."
"That is not important in real projects."
"We never needed that." (said defensively)
