Hard vs Soft Skills Recruiters Filter For

Writing a Resume Summary That Survives Screening

Open with your book-of-business size (ARR or number of accounts), your primary CS platform by name, and your best NRR or churn-reduction metric — these are the three signals a VP of Customer Success scans for in the first seven seconds on Greenhouse or Workday. Avoid adjectives like 'passionate' or 'results-driven' that consume character space without passing keyword filters; replace them with named tools and dollar figures. Include at least one expansion or upsell outcome alongside a retention metric to signal commercial ownership, not just reactive support. Keep the summary to 40–70 words so it renders as a single parseable block across Workday, iCIMS, Greenhouse, and Lever without truncation.

Mistakes That Get Resumes Auto-Rejected

These mistakes show up most often in Customer Success Manager resumes that get downranked or filtered out before a recruiter ever sees them.

• 1

  Omitting the CS platform name entirely — resumes without 'Gainsight,' 'ChurnZero,' or 'Totango' score below keyword threshold on Greenhouse and iCIMS recruiter searches before a human ever reviews the application.

• 2

  Listing churn reduction as a responsibility rather than a quantified outcome — phrases like 'responsible for retention' do not pass semantic scoring on Workday or Lever, while '14% churn reduction across 45-account portfolio' does.

• 3

  Failing to state book-of-business size in ARR or account count — hiring managers cannot benchmark seniority without knowing whether you managed $500K or $5M in recurring revenue, and ATS ranking deprioritizes summaries without dollar figures.

• 4

  Using a two-column or table-based skills layout — Workday's parser scrambles column order into garbled text, causing platform names and certifications to disappear from the structured candidate record before recruiter review.

• 5

  Describing only retention outcomes with no expansion or upsell metrics — in 2026, CSM roles carry NRR targets and commercial ownership expectations, so a resume showing only churn prevention signals a reactive support profile rather than a revenue-generating one.

• 6

  Placing contact information inside a Word document header or footer — Workday, Taleo, and iCIMS parsers frequently skip header and footer content entirely, producing a candidate record with no email or phone number and guaranteeing the application is never actioned.

• 7

  Keyword-stuffing platform names in a skills list without contextualizing them in experience bullets — modern semantic ATS layers on Greenhouse and Lever penalize isolated keyword lists and reward resumes where tool names appear in proximity to quantified outcomes within the work history section.
