Mukiha seems odd this happened to this extent i think there must have been some other reason as to why every-one was late? Could it be they way you formated the advert that even jobseekers did not take you seriously? Your email, name of company? You might have scared some people you know? I am not justifying the lateness but it's the extent that baffles me something else was inherently wrong perception maybe!!
However coincidentally spent the whole Friday interviewing, draining process i must say, however unlike maybe back at home, here the canditates have rights, ie: can reshedule the interview date to suit time best fitted for them, they can be running late and you have to accomodate them when they come however some form flexibility is prudent and i too believe there is some good in every-one irrepspective.
That said time-keeping is a trait that does not seem to exist unless of-sourse you buying some frothy liquid and burnt meat then some-one will got to the extent of "booking"a table for you complete with 5seats the place being jam-packed notwithstanding..
The greatest danger in times of turbulence is not the turbulence; it is to act with yesterday's logic.
