Anecdotally I have to agree with you. When I worked at Microsoft as a Cloud Solution Architect, my job was to help companies adopt the Microsoft cloud. There were some companies at a fairly famous startup accelerator which everyone here is familiar with who I was already engaged with when a new colleague also started helping companies out of this accelerator. I was quietly doing my job and helping solve problems, he made a big fuss about how he got Microsoft's foot in the door at this accelerator. Naturally he got tons of accolades and even a bonus for his work. This need to constantly be selling yourself internally was ultimately what lead to my departure from Microsoft. I'm here to solve problems, not to talk myself up as the savior of the world. It's also why I much prefer working with startups. Your work is much more evident and you aren't constantly having to tell everyone what you've done.
