I was once ghosted mid interview day. They left me in conference room and completely forgot. I was going to walk out after 30 minutes but I just wanted to see how long I could stay there. It took them five hours. And this was in a “highly secure” building so not sure how they invite someone to interview and let them just hangout inside the building for five hours.
Presumably the Yucca plant in the corner put on a spurt of growth after your visit?
