Agree with ANightWatcher - it really is laughable that we would be using this voluntary position as a stepping stone to anything else.
I have an established career of 20 years overseas, don't need another "job".
I applied for the Night Watch as I knew I would be able to pop in and out, taking over from MNHQ in the wee small hours. As a PP mentioned, there were quite a number of applicants, but I can guess why they chose me - I am boring, don't post much, tend to report stuff (and get it right about trolls - can spot them a mile off after 10+ years on MN), I have moderated another forum (voluntarily, natch), I have counselling training (although that is not my career) so I won't be freaked by threats of suicide etc. , I know the site well and have 10 years of experience here, so have a feel for the place, and am confident that I act in the famous "spirit" of the site.
Its always evolving and nothing really surprises me about the changes that naturally happen in a huge site like MN.
okay then, that's enough from me - see you again tonight 
Respect to the all the other Night Watchers, by the way!
