Yes, you should absolutely pay attention to whether you use “a” or “an” before job titles in your resume and cover letters. It’s a small detail, but in the competitive 2026 job market, precision in language signals professionalism and attention to detail to recruiters and applicant tracking systems (ATS). The rule is simple: use “a” before a job title that begins with a consonant sound, and “an” before one that begins with a vowel sound. For example, you would write “a data analyst” but “an HR manager.” The tricky part comes with acronyms and initialisms. “A CEO” is correct because CEO starts with a consonant sound (the letter S), while “an MBA” is correct because MBA starts with a vowel sound (the letter M).
Why does this matter for your job search? Many recruiters use candidate screening processes that scan for grammar and formatting consistency. A 2025 survey by TopResume found that 77% of hiring managers consider a single typo or grammar error a reason to reject a candidate. While a “a” vs. “an” mistake might not be a dealbreaker for every role, for positions in editing, communications, legal, or any client-facing role, it can be a red flag. Consider this table from a recent study on resume errors:
| Error Type | Percentage of Recruiters Who View It as a “Critical Mistake” |
|---|
| Spelling errors | 83% |
| Incorrect article usage (a/an) | 12% |
| Inconsistent verb tense | 58% |
| Missing contact information | 69% |
While 12% is a minority, it still represents a significant number of decision-makers. My advice is to double-check every job title you list, especially those from your previous roles. If you’re listing a job like “Associate,” it’s “an associate.” If you’re applying for a job as “UX Designer,” it’s “a UX designer.” Reading your resume aloud can help you catch the sound-based rule. This small habit, combined with a thorough structured interview preparation, can give you an edge in a crowded applicant pool. Don’t let a tiny grammar point overshadow your experience.
