i, personally, am not insulted. It reflects on cu that they choose to admit students in this manner, not me. I simply find it unprofessional. Imagine if it were a job interview and they told you could hear anytime after the interview, but possibly as late as 6-7 months with zero communication in the meantime. I'd laugh my way all the way to another job.
Applying only to cu and staying on the waitlist till august last year, happy or not, is irrelevant because you didn't have a choice. You could either remain on the list at cu and reapply, or not remain on the waitlist and reapply. Great argument.
Weather applicants get the chance to interview is also irrelevant. What people are (rightfully) complaining about is cu's delay in getting decisions out when we repeatedly told (at interview days) that decisions could be anytime between oct. And mid-march. That has nothing to do with someone's desire to attend cu. Quit comparing the two.
All of this said, cu is a great school and i wouldn't let the delay in admissions decisions determine where i choose to attend schools.
