What goes on during a 12 hour interview?

[MTK]

Snyder's interviews reportedly can go on for 10-12 hours which leaves me wondering... what in the hell goes on during these marathon interview sessions?

I once had a 4 hour interview for a job, but it was split up between several different groups of people, but either way it was very mentally draining.

I'd love to be a fly on the wall during a Snyder interview.
