You will probably disagree, but I see 1:1s with my manager as an opportunity to schmooze and re-iterate my accomplishments (I tend to be good at my job). I also tend to be an introvert, but I can turn on the charm as well as the bullshit if it is worth the effort.

Basically, I try to engineer 1:1s in my favor if I can - usually only upside opportunity in my case. If I can't, I would probably avoid them.
