Who we do not hire is just as important as who we do hire. We do not hire non-native speakers of English as our experience shows that quality editing stems from an editor’s intimate knowledge of a language. We do not hire people who demonstrate errors in their English grammar during their screening test. We do not hire editors with strong English grammar but who lack subject matter knowledge in a particular field. We do not hire editors who focus only on correcting grammar; we require editors to focus on clarifying authors’ intended meaning. We do not hire unethical individuals; our integrity and that of our clients is of paramount importance to us. We do not hire people who lack an appreciation or interest in science and research.
