PMs do get multiple opportunities to shine within their org at Cisco Systems. If the project result and impact is positive, expect to receive great appreciation and monetary benefits (this holds true for any company for that matter). Managers at Cisco are supportive, and encourage PMs to work on their development goals. You also have a lot of leeway to attend trainings or complete certifications if it helps in career progression.
Having said that, Cisco is a technology heavy company, so the career progression for an engineer may be much faster compared with a Project Manager.
