Hey flx, how can you be warned if you don't even work there? What can they hold over you? I don't get it. Besides, everything you have ever posted about CS has been positive (except your comment that you've been "warned").
I personally will share anything and everything about my interview experience with them, including why I turned them down. I think anyone interested in working there, or anywhere else, should know all the positives and any potential negatives before showing up to work. This kind of information is needed to make proper decisions. EVERY job has its pluses and negatives (although those at jetBlue won't admit it...). What was an negative to me might not be a negative for the next applicant. So, flx, I say share what you have for the betterment of someone else's career at CS.
