TLDR; Be objective

  - evaluate yourself against an objective rubric => medium has one (here: https://docs.google.com/spreadsheets/d/1EO-Dbsayn8Nz9Ii3MKcwRbt-EIJ2MjQdpoyhh0tBdZk/edit#gid=2049640133), but you can build your own and get feedback
  - list out your accomplishments, things you've done that you take pride in. compare these skills/accomplishments against what a qualified candidate for that role would have have
  - Ask your former employers or managers about your strengths and how they would level you
  - Read the army doctrine of leadership. Understand how leadership works in large organizations, understand what poor, good, and great performance is.

... I would personally add that soooooo many people in leadership positions are just making it up as they go. Especially at mid to lower level leadership/management roles. A company with a great product can literally have the worst management/ leadership possible and still be fine, so don't feel like you have to have the world on your shoulders. Good leaders work to define what needs to get done, and enable their people to be able to accomplish these goals. So just go for it!
