我听说的也是8-12周至少。今天在gmatclub的论坛上看到有人10月6号提交的今天刚拿到interview,所以还在发应该。This is from the CBS website:
After submitting my application, when will I receive a decision?In a given application season, the Admissions Office will begin reviewing January and September Early Decision applications once all required materials have been received, and will begin reviewing September Regular Decision applications in December, again, once all required materials have been received. We work to release decisions in a timely manner and decisions can be rendered at any time. Please note that an invitation to interview may extend the review process beyond our 8-12 week goal.
