When SeekOut returns Github candidates, you'll see a combination of their public profile data (title, location, company, etc.) and their Github contributions and repositories.
Next to each repository, you'll see their contribution rank for that project.
By clicking on the name of the repository, you'll get to a page that has all their code contributions for that project. You or your hiring manager can click on any of these to see the actual code the candidate has written.
Like any candidate you find in SeekOut, you can get contact information (verified work and personal emails, as well as social profiles), add them to a project, or export their profile data to a spreadsheet.
