Ask HN: X Years of 1 year of experience. What to do?

I’m sure most have have of this trope (https://news.ycombinator.com/item?id=4627373) and that’s kinda how I feel right now.

A lot of jobs I see at my YoE are senior level and use terms like “domain expert” that I just can’t read and say “yeah this is me”. I just can’t imagine performing in roles like this. I’m not an expert at anything, besides maybe figuring out how to figure out things I want to do. At the same time, I don’t feel much like a junior or anything. I have very cursory understanding of a lot of stuff, but a large swath of it is useless because I don’t have any experience back it up.

What are the typical moves for someone in this sort of situation.
