>he finally finished his nominally 12-month master's degree there

A Sloan SM/MBA is 2 yrs (nominally and actually). There is also a 12 month SM/MBA for "senior executives", so that's probably what is being referred to. But in that case, it wouldn't have been him "finishing" the degree program he had left (because he would not have been taken as a senior executive then), so they probably applied the credits he did have to this other program for which he would have to write a paper anyway.

(as a side quibble, MIT only started offering "an MBA" in the '90's (purely for job-market name recognition) and prior to that time the (same) degree was called SM Management, which is what his original program would have been. the SM is technically "better" because it entails also writing a thesis)

He visited a company I worked at when I was fresh out of school, and he was brought by my office impromptu to see what I was working on. my software crashed immediately, and he laughed, in a friendly way, but didn't ask for my resume.
