An Agile project manager leads differently. APMs use the Agile framework, created in the 90s, to create and manage teams. As an APM you will be less concerned with hierarchy and top-down leadership. Your leadership will be based on 4 main values; being team-focused over tools-focused, using working software over extensive documentation, collaborating with customers over impersonal contract negotiations, and being agile and flexible in the face of change.
Outside of certification as a project manager, a recruiter will need to see Agile certification. So ensure all your Agile qualifications are clearly listed.
