Hey. Good question. I think it’s a combination of what you probably already have: your CV, your LinkedIn profile (with recommendations if possible). Other things like a website, or a link to blogging would support that I’d hope. It should be enough to tell the story of who you are and how you think and interact with the community. I will be using this blog for example, as it demonstrates (I hope) a desire to challenge the status quo, the ability to debate, communicate my ideas, take criticism etc. It shouldn’t all be about one document.
