You should also include information about promotions in this section. When listing your responsibilities, start with the most valuable experience first, since the employer will likely be skimming your resume top-down.
There is not one resume format that works for everyone. There might not even be only one resume format for you and it could benefit you to have multiple formats of your resume available. For example, if you’re applying for a job and you don’t know whether your resume will be submitted through ATS, submit both a chronological resume and use a functional resume for your in person interview.
