Booth acceptance verification process

Hi everyone. i applied to Booth in R2. just two questions:

1. Does Booth have a verification process for admitted students (ie to verify employment info, dates, university grades, etc.)?
2. If so, how long does this verification process last? How much time between the day you are accepted and when the verification process is fully complete?
3. If i am accepted on March 27, and then voluntarily quit my job in the first week of April, could this jeopardize my acceptance? Should I wait to leave my job until the verification process is complete or does it not matter?

thanks
