I'm not sure what field you're in but if you're reasonably competent, being transparent and honest with what gaps there are in your knowledge can be an attractive trait for a candidate. Someone who's forthcoming about things they're unsure about is someone you can train faster because they recognize that they don't know everything...and that trait keeps them open to learning and open to better solutions too. Sometimes people want to hear that you struggle with the same things.

All of this probably goes out the window in hyper-competitive fields but in my field for example (software engineering) where there's a labor shortage, I've found this to be the case anywhere outside of the companies that just want to test how well you remember your Computer Science degree.
