I joined Cisco EIC and knocked out a long withstanding issue within Cisco early. It garnered attention from my director and everyone on my team thought I was a superstar. My director, manager praised me endlessly. My manager said I was aligned for a promotion and put me on a new project unrelated to my skill set. I don't know why he took me out of the role I was hired for as he still had positions for it and ended up hiring other people to do what I did previously.
He gave me objectives to complete on the new project and I did everything he asked to obtain a promotion. When it came time for review he suggested I needed more "visibility" that I was doing these wonderful things but it wasn't being seen by anyone and suggested I improve my power point skills. He made it clear doing more power points was super important for promotions. This struck me as really odd, but I went through the motions and continued to meet the objectives. The promotion never came despite him promising it would lead to one. Instead, I was moved to multiple different managers, different orgs, was told to continue the same project. None of the new managers knew what this project was but thought it was important and asked me to continue to work on it and gave me new objectives. I met every single objective laid out and went beyond. As I continued to change from manager to manager I got placed on a new team, was there for a short time and got laid off before my new manager ever got the chance to get to know me. This has been my experience as a young under 30 employee at Cisco.
