2. Are you guilty or not guilty? The judge or magistrate will explain what those pleas mean legally, but did you do it or not? If you did it, grow up and be an adult and take responsibility.
3. Yes it will be on your record.
4. No one here knows the answer to this. Will your current employer be looking?
