my resume is a little on the exageration side. mainly so that when hiring managers read my resume and assume i'm lying they'll hopefully end up with a picture of me thats about at the right place.
Also I think that appearing to be better than you really are is a skill that companies are interested in having on their work force. So being frank and transparent could possibly work against you, especially if the hiring manager knows youre being frank and transparent.
I think you are over thinking this. I interview a lot of people for engineering positions. If I think you're trying to deceive me, or I think you've lied on your CV, you're getting a much bigger black mark than if you struggle a bit on the technical tests.
An aside: if you consider a $30,000 wage bracket a senior developer might fall in to ($80k-$110k), I see little correlation between what people ask for and what they 'deserve' based on their technical skills (inside of that bracket)
