My ethics are struggling with my play to win attitude.
If you have ethics there is no struggle, as others above have said. This is the pitfall of an open forum that allows public viewing such as you have experienced. We see this every day with the elections as people pit against each other not on their own merits but the faults of the other person. You say you are the best, then walk in there believing it and sell yourself. I see this often as other people want the work done for them. Instead of doing the research on what he needed to know he asked someone to provide it for him. I think if you follow your ethics and trust your merits and abilities you will win a true victory and sleep well at night too. Best of luck to you in your interview.
