OK I got an email to call them on Thursday or Friday. To be honest I don't know if I am going to. I am kind of tired and a bit irritated by the whole process. Also on my first interview they told me that decision will be made by the end of the month, they did not mention anything about another interview. If I really cared about MSOR and if it was my only option I would have freaked by now. I am 90% sure that they forgot about my first interview and this one will be the same. Really unorganized application process with Columbia.
