> [paraphrasing] "What if I [am not good enough]? (And someone discovers this?)"

Then you learn a bunch of stuff from being out of your depth, get a bunch of money for your trouble, and - depending on the internal political strength of the person who finds out - find another job. It's not the end of the world.

The worries you talk about, however, are things that a lot of people have to varying degrees. To learn is to feel somewhat out of one's depth; to be confused. If you already knew all the answers, I find it hard to imagine that the work would be particularly interesting. Taken as the general case, to know enough is to be done with learning and thus to stagnate. They are worries that you'd still have if you were exactly where you were going to get the most advantage.

You don't know enough to immediately solve your challenges - that's why they're challenges rather than typing exercises. Chances are that no-one else there, at least no-one who isn't wasting their potential, does either.
