Questions for proofreading, QA and content-editing roles, with answers that show method rather than talent.

1
What is the difference between proofreading and editing?

Proofreading finds errors in a finished text: spelling, grammar, punctuation, formatting. Editing changes the text itself for clarity, structure or tone. Say which you are applying for and that you can tell the difference when a client asks for one and expects the other.

2
How do you proofread a long document?

In passes: one for meaning, one sentence by sentence for grammar and agreement, one for punctuation and formatting. Describe how you keep your place on screen and how you handle fatigue.

3
Which style guide do you follow?

Name one you know (a house style, or a common published guide) and say that you follow the client's guide first. The right answer is consistency within the document, not a particular guide.

4
Find the error: 'The team of managers were late.'

Subject is 'team', singular, so 'was late'. Explain the rule: find the head noun of the subject, ignore the phrase after 'of'.

5
How do you handle a writer who rejects your corrections?

Separate errors from preferences. For errors, cite the rule. For preferences, note them and let the author decide. Keep the tone neutral; you are checking the text, not the person.

6
What is your detection rate?

Give a figure from practice with how it was measured: "About 90 percent on timed tests with planted errors, with one or two false flags." Then say what you are working on.

Practise out loud. Say each answer once as written, then again in your own words with your own number or story.

Have a number ready. "My Proofreading score is at benchmark on a timed test" is a stronger answer than "I am good at it". Take the test and quote the result.
