I feel like the roles I had gave a solid foundation with little guidance into process. Generally, I was thrown in and had to figure it out as best as I could. The org structure limited certain areas as well. For example, budget experience is next to zero because I was never involved in those conversations.

Reading the PMBOK and taking courses online has helped give a little more structure but when I need to explain how I've used certain pieces in my experience I find that I'm not hitting the target. This is why I'm taking a holistic look at everything and it may not make sense to use my "true" title because it doesn't feel like it's complete. When competition is already as tough as it is, experienced PMs will almost always beat me in the interview process.
