How should I prepare for an editing or proofreading test during a job interview?

Practice the process, not just spotting typos. Use a short passage similar to the kind of writing in the role, such as a report, web page, or email. Give yourself a time limit, but don’t assume every test has the same format: read the employer’s instructions carefully, and ask a brief clarifying question if something important is unclear.

Try this deliberately imperfect practice sentence: “Our team have reviewed the draft, it explain the new process clearly. Please send feedback by Friday, so we can make any final change.”

A sensible edit is: “Our team has reviewed the draft; it explains the new process clearly. Please send feedback by Friday so we can make any final changes.” The first sentence has a subject–verb agreement issue and a comma splice; the last has a singular/plural mismatch. The comma before “so” is an optional punctuation choice here, not the main correction. Identify definite problems before spending time on preferences.

Use separate passes, and make each pass answer a different question:

1. Understand: What is the text for, who will read it, and what instructions or style rules apply?
2. Check meaning and structure: Are the points understandable and in a sensible order? Flag unclear passages rather than inventing what the writer meant.
3. Correct definite errors: Review grammar, spelling, punctuation, names, numbers, and consistency. Distinguish errors from acceptable variations.
4. Polish selectively: Improve wording only when it makes the text clearer, more concise, or better suited to the stated audience.
5. Proofread the edited copy: Read the final version afresh, checking that your changes did not introduce new errors.

If time is short, prioritize changes that affect correctness or meaning. Avoid changing a sentence just to demonstrate activity. An edit should solve a problem; if you can’t name the problem, consider leaving the wording alone.

Check the instructions first. A supplied style guide, tone requirement, or formatting rule may settle the choice. If none is provided, aim for clarity and consistency while preserving the writer’s meaning and voice. Don’t silently change facts or fill gaps with guesses. You can flag an ambiguity with a short comment, for example: “Please confirm whether this date refers to the launch or the announcement.”

For practice, label each proposed change in your notes as error, clarity, consistency, or preference. Review preference changes critically: keep one only if it serves the brief. If the test permits comments or tracked changes, use them to explain consequential edits; otherwise, follow the requested format and keep any explanation brief.

Before starting, note the time limit, requested output, audience, and any style instructions. Divide the available time into rough stages rather than spending it all on the first paragraph. For example, reserve time for an opening read, a focused correction pass, and a final check; adjust those stages to the passage and instructions.

Keep a small decision log if the format allows it:

• Change: “team have” → “team has”
• Reason: subject–verb agreement
• Change: “it explain” → “it explains”
• Reason: subject–verb agreement
• Query: “the second release”
• Reason: unclear which release is meant; needs confirmation

At the end, check that every requested section is present, edits are visible in the requested way, and you haven’t introduced a new inconsistency. If asked to discuss your work, explain a few representative choices by naming the issue and how your edit addresses it. You don’t need to defend every comma or present an optional preference as a rule.
