First thing first. If you google this question, very likely you would result in bunch of hollow advice like, 'just be yourself, they are also human beings'. Or something like, 'they are more than happy to offer as long as you ask'.
However, what I observe from reality is that this is totally not true. In reality, even as a capable employee of my boss, my boss would only think about me when he needs me. Other things, he doesn't care at all, and tries to cut every friendly conversation short.
Soon I grow to realize the seniors just don't bother. I could be wrong, but the impression I got from numerous attempts is like, juniors are just like disposable tools for them to achieve their next great bonus or career aspiration.
Maybe I'm too pessimistic, but it seems to me to be a problem. Thus, I'm seeking honest answers to how to properly network with seniors within the company (assume a large organization). I want the 0 to 1 process. But things become very difficult, as seniors judge juniors on the ground of 'what can you do for me?'.
To simplify things and be very honest, the goal of networking would be for career progression. It exists, no matter how you deny it.
Edit: some people ask for rigorous definition of juniority. But as the discussion goes, it is never definite. Despite the terms 'junior' and 'senior' are always implicitly consensed, but for the sake of convenience and rigor, a one sentence assumption to facilitate discussion would be: junior is a relative term, relative to N+2 or up. Though junior is more commonly referred to those with <3 years of work experience. But it would be good to see both cases discussed if possible. The focus here is the rank superiority in general.
