On the job I have always been dependable, competent, good with time management, communicative with my boss on where I'm at, as well as communicating when there are issues and stating those less palatable things. Diplomatic, yes. Deemed good with communication and navigating that; with ofc occasional clashes, but those have been rare.
Not a terribly excellent team player though, meaning I will rock the boat or question something if something doesn't make sense to me or I think something isn't a good idea. I have never desired to be the focal point, dislike running meetings (even though have had a previous job where that was required of me, which was very stressful), and don't often speak up in meetings/so on, but I'll be the person who points out one or two things I see as key, summing things up and so on.
I'm not highly personable in a social sense on the job, though; I don't go out of my way to befriend myself to others, I keep to myself often. I also don't care for the 'obligatory' 'good mornings' and chit chat; I'll chat with people on my own terms, if I'm in the mood, if it's coming from a place in me where I really want to chat or something. I imagine as a result, I may confuse some people, as I may seem unfriendly/closed off for a while, then if I chat with them and am in that mood, I'm suddenly more chatty and expressive, bubbly even, engaging, or go into mini-rant-frustration-mode if something work-related. But mostly I have never used work as a social thing... just work, keep on good terms with everyone, mostly stick to myself, go home. Maybe a lot of it is that I've never had a job that really is 'me', though, it's always just been something to have a paycheck, thus I can't relate to the environment itself or most of the people I work with, and I inevitably over time can't tolerate being there anymore. This is a recurring problem for me and I am still needing to address it more effectively/in a more longterm sense.
But throughout that whole process I'm always a good employee (i.e. viewed positively by boss and others), also aware of office politics/vibes; if I eventually come to dislike the job/vibe/reality, I exit the job prior to the point where I'd cease being able to do it.
