That's the distinction between being good for you and being good for your co-workers/company. When I'm hiring someone I care about them being good for co-workers and the company.
Maybe I should clarify that these aren't things I would do on the job. I engaged with co-workers through volunteer work, at those goofy socials at the Chamber (which I refuse to do now), going out for lunch or drinks with folks I met in the halls, etc.
Either way, to me work isn't just going in, punching a clock, and cranking out canooter valves and cagibilt rings. As a program manager, I've always had an appreciation for the relationships and motivations of others. I do the canooter valve thing too, but I always enjoyed the brainstorming sessions and mind maps, and solving problems and making deals happen. I dunno, networking is part of the job if you ask me.
