Thought I'd offer my thoughts for everyone that has completed an interview, received feedback, and is now waiting on a decision. I'm in the same boat...although I haven't been waiting nearly as long as some...interviewed on 4/2 and feedback submitted on 4/6
Anyone admitted between Feb 18th and April 2nd has until April 16th to submit their deposit. By now, almost all other schools have released R2 decisions so CSB is likely waiting until the 16th to see how many deposits they receive before releasing the next wave of decisions. Obviously the fewer the acceptances at CSB by the 16th, the better for anyone still waiting, but I would think they still plan to admit a certain number regardless.
The last despoit deadline was March 4th and if you look back at the thread around that time, you'll see a few decisions start to go out during the days leading up to March 4th and then a flurry of news over the following week. Since then there have been a few decisions released but pretty sparse for most of April as I really think they are waiting on the April 16th deadline.
Far from an exact science but this logic seems more consistent than trying to gauge how many weeks it has been since your application went complete or you received feedback on the interview. Best of luck to everyone still waiting. Hopefully we start to hear some good news late next week or on April 19th/20th.
