It’s easy to go to someone’s sites and portfolio to get a sense of what they’re about. Product Managers still appear to be stuck in the “Let me tell you how awesome I am” rut, though. This is a generalization, of course, but what I’m mostly seeing right now is resumes that excel at vagueness.
I’ve seen many of those types of resumes over the years. It makes you sit back and say, “what does that even mean?”
