Chronological Format: The Default for a Reason
The reverse-chronological resume lists your most recent job first and works backward. It's what 90% of recruiters expect, what ATS systems parse most reliably, and what most hiring managers find easiest to evaluate quickly. If your work history is consistent, relatively recent, and relevant to the role you're targeting — use this format. There's rarely a reason not to.
The only situations where chronological hurts you: significant employment gaps that would be glaringly visible in a timeline, or a career history so scattered that the pattern of jobs doesn't tell a coherent story.

Functional Format: Why Most Experts Say to Avoid It
The functional resume leads with a skills summary and buries work history at the bottom — sometimes barely listing it at all. The intent is to lead with capability rather than timeline. The problem: ATS systems frequently fail to parse functional resumes correctly, scoring them low or dropping them. Recruiters distrust functional resumes because they know they're often used to hide something.
A combination resume achieves everything a functional resume tries to do — skills-first framing, de-emphasized gaps — without the ATS penalty. If you're tempted to use a functional format, build a combination resume instead — you get the skills-first framing without the ATS penalty.
Combination (Hybrid) Format: The Best of Both
The combination resume opens with a strong skills or achievement summary, then follows with work experience in reverse-chronological order. This gives you the keyword-dense, qualifications-first opening of a functional resume with the timeline credibility and ATS-readability of a chronological one.
This format works exceptionally well for career changers (emphasize transferable skills before the timeline), experienced professionals with dense histories (lead with impact), and anyone with a gap they need to de-emphasize (the strong summary draws the eye before the dates).

Format Decision Rules — Simplified
Chronological. No debate. Standard order, most recent first, clean timeline.
Combination. Lead with transferable skills and achievements, then show the timeline.
Combination or chronological with years-only dates. Never functional — it raises more flags than it solves.
Chronological with education near the top. Skills and projects can precede work history.
Chronological or combination. Emphasize scale and P&L early. Two pages expected.
Chronological with a strong technical skills section after the summary.
