Originally didn't get an e-mail back after on-campus interviews. Out of the blue got an e-mail roughly two days before the second round of interviews stating that there was a spot open for me if i would like to attend. 2nd round of interviews were a bit more intimidating than the first, but after building some chemistry with the interviewers I found it to be just like the on-campus ones. Be prepare to answer a barrage of technical finance, and behavioral questions. Didn't get the offer, but overall was a great learning experience.
