So if somebody during an interview asks a question, i.e., How much did you make at your last job? The answer they are looking for is, "I made $ x.xx an hour."

There are interview coaches that can put you through mock interviews so you can practice, and help you come up with good answers to really common interview questions. Maybe look into that.

Preparing for an in-person job interview is like preparing for an exam. Study and prepare your answers (and questions) ahead of time. Interviewing is a skill that should be practiced in order to be mastered. Just like playing the guitar or learning how to do anything. The cool thing is that no matter what the job, the questions are going to be grouped in different areas. There's only so many ways to ask a question! So the answer to "Tell me 3 of your weaknesses" can be the same answers to the question "What challenges you?"

There are lots of free resources on youtube to help. Just search for "How to prepare for a job interview". Here's a users channel to get you started. His suggestions are good. There are lots of others as well!
