the lowest rung on the ladder
The person with the least amount of experience, authority, and/or influence in a social or corporate hierarchy. It can be a little daunting going from being a senior in high school to the lowest rung of the ladder again as a college freshman. I know I'll be the lowest rung on the ladder with this internship, but it will at least give me a place to start my career!

get (one's) bell rung

ring (someone's) bell
1. To strike someone with a violent blow to the head, especially as might stun or concuss. I would have rung that guy's bell if I knew he had been trash-talking you. Sarah's likely to ring your bell if you keep harassing her like that.
2. To be enjoyable, preferable, or satisfactory to someone; to be or provide something that someone wants. A: "How's that new book you're reading?" B: "Eh, it isn't really ringing my bell, to be honest." I'd rather go see the action movie, if that's all right. Dramas just don't ring my bell.
3. To sexually attract or arouse someone; to bring someone sexual gratification or satisfaction. That redhead from across the bar has been ringing my bell all night. He looks mighty fine, all right. I'd like to take him home and ring his bell!
