When I'm setting up my LinkedIn or presenting myself during an interview, I'm not sure how to seem confident without coming off as cocky. I need to sell myself, but I don't have any experience (as I've mentioned here before). So if I tried to write a summary on LinkedIn to create my own personal brand, won't it just come off as a lot of big talk with no real substance?
On one hand, I'm worried about being insecure, and on the other, I've heard some employers tell stories about guys who are all talk.
