First a phone screen with the Recruiter, then a 30 min phone call in which I had to remind the hiring manager that she was late for her next meeting. Next I met with two senior folks in the department. After a day, they scheduled me for 5 additional Zoom interviews, over two days. I met with the first two on Monday, sent my Thank You emails. Tuesday I waited for the first of three interviewers to join the Zoom, and nearly 10 min into the 30-min slot I emailed the Recruiter asking if the person was running late, or not going to make it -- I'd silenced my phone for the interviews, so I missed her return call, but her vm said "sorry we had to cancel, we'll reach out to reschedule". That's 10 days ago, and the Recruiter hasn't responded to 2 emails, and a vm I left. This is a senior level position; the fact that they'd completely ghost a candidate who had already been through three rounds, then having the candidate wait 10 min for an interview they forgot to cancel is asinine.
