"I know nothing about code, give me 3 day" you did not need to raising flag that hard, now how do the poor intern suppose to win
And even if she win, win against someone know nothing about code 3 day ago ? that isn't sound convincing for the hire. Even if reputation of the genius is well know in this company, she is on the side of suggest this new hire.
seem like a lose-lose situation. Why not just let her go against someone who already work at company, no bias, and it should be 100% make her qualitied
