RE: Scholarship
As aerien mentioned, if you have a scholarship offer from another school but would still like to attend Yale, contact the admissions office and tell them about this - it won't hurt your candidacy if you ask politely

RE: Torn between 2-3 schools
I highly suggest making your decision after the welcome weekend. If you would like to reach out to folks with similar background/career aspirations, message me and I can try to put you in touch with some 1st/2nd years.
Can't speak to the 2016 employment report, but the 1st/2nd years, including myself, have access to a "who went where" spreadsheet. Can give you some insights if you have specific questions.
Feel free to message me if you have any questions.
