It's so easy to inflate your role on a project and what you contributed and the people who are best at it are usually also able to talk, talk, talk.
The first interview question I ask is so easy that I don't think anyone should be paid to write software anywhere if they can't solve it. And yet, I have candidates with plenty of nice bulletpoints like your second one on their resume who can't solve it or take 30-45 minutes to solve it. Good candidates take less than 10 minutes, very good ones take less than 5.
