How to write Chief OF Staff (COS) Resume

Crafting a resume for a Chief of Staff position requires a careful presentation of leadership, strategic planning, communication skills, and the ability to work across various departments and stakeholders.

Expert Tip: Make sure you highlight your accomplishments in a way that will appeal to the hiring manager.

 This means focusing on skills that are relevant to their industry and company. Discuss your skills and abilities in each area of expertise. Include both technical skills and soft skills such as leadership, communication, and teamwork. nclude any awards or recognition that you have received for your work, as well as any other notable achievements (e.g., patents).

reverse chronological format is most appropriate for a COS or other position with a high number of years of experience.  A reverse chronological resume includes the header with your updated contact details, professional resume summary, work experience, and additional skills and education sections. It should also include your most impressive achievements and honors. Reverse chronological resumes can help you win the approval of Reed Hastings and earn an interview. 


Select the Right Resume Format

Choosing the right resume format is crucial to presenting your experience and skills effectively. There are three main resume formats to consider:

  • Chronological: This format lists your work experience in reverse chronological order, focusing on your career progression. It is ideal for chief of staff  with a steady career path in the same industry.
  • Functional: This format emphasizes your skills and achievements rather than your work history. It can be useful for those with career gaps or transitioning to a chief of staff  role from a different field.
  • Hybrid/Combination: This format combines elements of both chronological and functional formats, highlighting relevant skills and achievements while showcasing your work experience. It is suitable for chief of staff with diverse backgrounds and experiences.
