When I meet fellow devs, I ask what projects they've shipped. Roles are near-meaningless across companies and convey 0 information about what their work involves in my experience. I appreciate that OP learned something about the job through this article.

I agree, it feels like roles help the most by getting you through the recruiter and in front of a hiring manager. Which is unfortunate.

This isn’t foolproof either and plenty of people can talk convincingly about running projects that they had little to nothing to do with.
