Hi, so I’m a sophomore in high school (in September) and I really would loe to go into the business field for college. My dream school would be Wharton of UPENN and I really want to start to looking for internships or jobs. I know how impossible it is to get an internship which is why I also want to look for a job that looks good for business, preferable something in an office environment if it is possible. I live in Jersey City and have easy access to manhattan. Thank you 
As a sophomore in high school an office based internship would likely be working in the mail room. Get a part time or summer job anywhere. It will make you aware of what the working world is like.
