Common Mistakes on Senior Software Engineer Resumes

  • Listing every technology ever used - Focus on 15-20 skills you can discuss confidently in interviews.
  • No leadership signals - Senior resumes need Led, Architected, Mentored. Pure IC bullets suggest you are not senior.
  • Missing scale indicators - Include users served, requests/sec, data volume. Scale separates senior from mid.
  • Multi-column layouts - They break ATS parsing. Use single column with standard headers.
  • Two+ pages under 10 years - One page. Every line should earn its space.
