Resume best practices have evolved meaningfully over the past few years, driven by the near-universal adoption of applicant tracking systems and, more recently, by employer use of AI-powered resume screening tools. The fundamentals of a strong resume haven't changed, but the formatting and content choices that actually get a resume through automated filters and in front of a human have.
Start with structure. The resume that performs best in 2026 is a single-column, single-page document for candidates with less than ten years of experience, and a two-page maximum for candidates with more. Multi-column resumes, fancy headers, embedded images, and creative typography routinely fail ATS parsing — even when they look beautiful to humans. The format that works reliably across ATS systems is a clean, left-aligned, single-column layout with standard section headers.
Section ordering matters. The strongest performing structure for most candidates is: contact information, professional summary (2 to 4 lines, not a bulleted list), professional experience in reverse chronological order, education, and a brief skills section. For candidates with deep technical specialization, the skills section can move closer to the top. For early-career candidates, education often sits between summary and experience.
The professional summary has replaced the old 'objective' section and is now an essential element of an effective resume. It should be three to four lines explaining what you do, what kind of role you're seeking, and one or two specific differentiators. Generic summaries — 'experienced professional seeking opportunities to leverage skills' — actively hurt. Specific summaries — 'Senior FP&A leader with 9 years building forecasting functions for SaaS companies in the $50M to $500M revenue range' — meaningfully help.
Experience bullets are where most resumes fail. The bullets that work consistently follow a specific structure: action verb, what you did, scope or context, quantified outcome. 'Led migration of 40-person customer support team to new help desk platform, reducing average ticket resolution time from 18 hours to 6 hours over 90 days.' Bullets without numbers are dramatically weaker than bullets with numbers, even when the underlying work is impressive.
Five to seven bullets per role is the right density for recent roles. Earlier roles can be compressed to three to four bullets or, for roles older than ten years, a single line summary. Most candidates over-include detail on early-career work and under-include detail on recent senior work, which is exactly the opposite of what employers want to see.
Keywords matter, but not in the way candidates often think. Stuffing the resume with keywords from the job description backfires — both because most modern ATS systems detect this and because human reviewers find it transparently manipulative. The right approach is to make sure the actual keywords genuinely relevant to your experience are present in natural context within your bullets, particularly the technical skills, methodologies, and tools you've actually used.
Length discipline remains essential. The single most common failure pattern in candidate resumes is excess length — three-page resumes for candidates with eight years of experience, four-page resumes for candidates with fifteen years. Compression is its own skill, and resumes that demonstrate it tend to outperform resumes that don't.
One last point that candidates often miss: the resume's job is to get you to the interview, not to communicate your full professional story. Treat it as a marketing document optimized for that specific outcome, not as a comprehensive autobiography. Resumes that try to say everything end up emphasizing nothing.
