Chinese languages

I am trying to recall a chengyu. This was the context: I was chatting to someone about the Chinese educational system and job scene and I asked if it wasnt difficult to stand out when there are that many people competing and she said yes and there is a chengyu for that.... but now I cant remember what she suggested. I would love to know if there is a good chengyu describing this situation. Any suggestions?

鹤立鸡群 has this meaning
