I have this problem - I am one man hardware department for almost a decade. I am interviewing now and people don’t want to listen to this. I designed everything and own everything. So I started lying having imaginary colleagues who co-designed the these things. Then interviews went okayish again. Some toxic places do not want teamwork. It is called here “spoon feeding”.
