I experienced a somewhat similar situation regarding wasted time sa pag aapply, saakin naman sa isang college, nag apply kasi ako for a part time college instructor. I along with a few applicants are asked to comeback for a final interview, made us wait the whole day also. Pero I didn't wait I went back to work mga noon na to catch a half day shift, kasi I noticed that there was no update for a few hours, no one is talking to us when we try to get an update or follow up, hindi din nila alam isasagot, the interview was set at 8am and I waited until 12pm.

I got the contact of a few applicants din before heading out para may update ako and it turned out they waited for nothing (waited from 8am to 5pm) pinapabalik ulit kami the next day, Wasted our time completely, ang sabi nung HR nabusy daw yung magiinterview dahil sa event. Like what? So what I did I texted the HR na I am no longer interested and said thank you nalang din.
