Three resume formats

Reverse-chronological
Experience comes first, most recent role at the top, each with bullets. It's what recruiters expect and what ATS parsers handle best.
Hybrid (combination)
A short skills or highlights section near the top, followed by a normal chronological experience section. Useful for career changers and people with a varied background.
Functional (skills-based)
Groups achievements by skill with little or no job history. Recruiters often read it as hiding something, and parsers struggle to connect skills to roles. Best avoided.

Which one to choose

Use reverse-chronological unless you have a specific reason not to. Choose hybrid if your most relevant experience isn't your most recent (for example, you're returning to a field), or if you're moving into a new field and have transferable skills to highlight. Even then, keep a dated experience section: employers want to see where and when you did things.

Section order

Experienced
Header · Summary · Experience · Skills · Education · Certifications / Projects
Student or new graduate
Header · Summary · Education · Projects / Internships · Skills · Experience
Career changer
Header · Summary · Relevant skills or projects · Experience · Education
Academic or research
Header · Education · Research experience · Publications · Teaching · Grants and awards

The principle: whatever best proves you can do the target job goes nearest the top.

Layout rules

  • Body text around 10–11 pt in a readable font; headings a little larger. Don't go below 9 pt to squeeze things in.
  • Margins of roughly 12–25 mm. Very narrow margins make a page look crammed and can clip when printed.
  • One accent color at most, used for headings or rules, with body text in black or near-black.
  • Consistent spacing: the same gap between every role, the same bullet style everywhere.
  • Bold for job titles or employers, not for random phrases inside bullets.
  • No photos, skill bars, or decorative graphics unless it's a design portfolio piece and you're sure the employer wants that.

One column or two?

A single column is the safest choice for online applications: text is read top to bottom, exactly as written. Two-column layouts fit more on a page and can look sharper, but some parsers read straight across both columns, mixing your sidebar into your job history.

A sensible rule: use a single column for portals and large employers; a two-column design is fine for email applications, networking and interviews, where a person reads the PDF directly. In QuickHunt, thirteen of the eighteen templates are single-column, and switching between them doesn't change your content, so you can keep both versions.

Dates

Pick one format and use it everywhere: “Mar 2022 – Present” or “03/2022 – Present”. Month and year is standard; use year only for roles from long ago. Put dates in the same position for every role (usually right-aligned on the title line). Avoid “Summer 2021” and “’19”.

Before

2019 – Mar '21 · June 2021 – now · Q1 2023 – present

After

Jan 2019 – Mar 2021 · Jun 2021 – Dec 2022 · Jan 2023 – Present

File format and name

Send a text-based PDF unless Word is requested. Check that the text can be selected and copied. Keep the file under 2 MB, and name it Firstname-Lastname-Resume.pdf. The ATS guide explains why these details matter.
