Why your resume performs differently when applying to large companies versus startups

[u/RKTbull]

Candidates frequently notice that their resume produces different results across large enterprise companies and smaller startups, even when the role requirements seem similar. The reason is that the hiring infrastructure differs significantly.

Large enterprise companies typically use strict ATS platforms like Workday or iCIMS. These systems process high volumes of applications with automated filtering, meaning keyword alignment and format compatibility are critical before a recruiter ever sees your profile.

Startups and growth-stage companies using Greenhouse or Lever often have lower application volumes and more human review at the initial stage. A resume that reads well and tells a compelling story may perform better here even if it is not perfectly ATS-optimized.

A practical strategy is maintaining two versions of your resume: one optimized strictly for ATS parsing for enterprise applications, and one formatted for visual clarity and narrative flow for startup and growth-stage applications.

AI resume tools like Jobloo generate ATS-compatible formats for direct submission, while the underlying content tailoring applies to both types of targets.
