Throughout my career I've worked in teams where everybody does everything and nobody really has the ability to claim ownership of a specific feature or successful implementation.
As I'm updating my resume, I find it hard to find something to claim as my primary responsibility or contribution. The things that I did contribute most significantly to would be so specific that it wouldn't be relevant to anybody who wasn't part of the organization or used the product.
Should I forego trying to list specific roles and responsibilities on my resume or is there an effective way to present this collaborative work?
