As a fairly experienced interviewer, having administered well over 200 both as an employee and an independent... these guys dropped the ball - hard.
If you are interviewing somebody, you are not there as 'yourself', you are representing the company and their engineering org, and by my understanding, it is exceedingly poor form to present the company as inconsiderate and to burn bridges. Even if you're having a bad day and the candidate is a poor fit, you suck it up and remain professional and collegial.
The one who walked out should be removed from the interviewing pool. Maybe they're a good engineer, maybe not, but if they act that way consistently then their attitude and self control are not cut out for interviewing.
