ActiveCampaign Customer Success Manager interview questions

I never actually got to do an interview. About 2 weeks after applying, I got an email that they'd like to do a phone screening; I went to sign up for a time slot, but the first available was over 2 more weeks out. I signed up anyway. Day of, I prepare like normal, wait for a call at 1pm. At 1:03, I get an email about how their needs have changed, even though the job is still posted. No wonder they're always hiring; there's no way to reach out to HR, and it seems like a mess. My guess is that a reminder popped up on the guy's calendar and he didn't want to be bothered at the moment. It's a shame to think that they're fine with treating people with such disregard.
