I'm not saying the poster got the job because she was a girl (or not), but the bottom line (imo) is that you have to play the hand you're dealt.

Some people are born rich, into high society etc and some are not. I don't see people unhappy that others are saying they "got the job because their dad was powerful".

Whether or not there was a real advantage doesn't matter. If there was a real advantage, well thank you, I'd take that advantage. If not, prove it. Either way, you still don't deserve to feel upset over it.
