Quitting job before R2 interviews

Hello Dudey,
First, the answer to your second question is easy - No, you should not "talk like you're still in it" if in fact you are not working at the time of your R2 interviews. Character and judgment are qualities that Admissions look at so in no way do you want to say something that's dishonest about your work status. If you are planning to quit your job prior to the summer, I suggest that you have a plan to do something constructive rather than just take time off to hang out.
Even if you are admitted to other top schools, when it comes time to interview for summer internships and full time jobs after your MBA, you'll need to account for any extended periods of time when you were not employed. What you choose to with your time after quitting your current job will reflect some of your personal qualities and you want recruiters to get the sense that you are a dedicated worker who will be an asset to their company. If, for example, you have worked straight through since college without taking any extended vacations then it would make sense if you decide to travel or do something else that you will enjoy. Think about what kinds of activities or experiences you can involve yourself after you quit your job and think about how they would be perceived by future employers. Hopefully this helps and good luck with your R2 apps.
Take care,
Dina
