I envisage the examination process being very thorough, with a combination of practical tests, in person cross-examination by a team of interviewers, essays, etc.

MIT could absolutely ask you any sort of question they would expect you to know, or ask you to do anything you’re expected to know how to do.

I envisage it being a multi-week process. I think for undergrad CS, maybe two weeks is enough? But it’s be up to the degree-granting institution how long they take and how it works. I can easily see it taking a variable amount of time too, depending on the applicant. A one-day multiple-choice vs a two-week hands-on assessment would mean the degrees would have quite different value.
