How in the hell what game mode your play'n??

I join a map but it does not tell you if is a king of the hill map and stuff like that team death match or what? I join a conquest map and when I got in it was Team Death Match. I instantly left the game because it was a Team Death Match game. I don't like Team Death Match. I need to know the game mode before I join a server. So what is the trick to find out what the game mode is be for I join a Server?
