Ok - so I can't say I actually went through the interview process because it never even happened. They reached out to me to schedule a first round interview. We scheduled it - I was available during the said time period. I waited at the scheduled time - 15 minutes pass, 30 minutes pass, 45 minutes ... an hour. I think you can see where this is going. No call.
So OK, things do happen. I email to reschedule. The person emails me back almost a week later (the interview was supposed to be on a Wednesday - I emailed that night. Didn't hear anything. So I emailed again on Monday morning, and they responded on Tuesday morning).
So the person said something came up, and they wanted to reschedule. No problem. I realize life happens. New interview is schedule for that Thursday afternoon.
No call. Nothing. At all. No apology. No email. No one following up.
So I emailed. I got a response almost a week later telling me that they are no longer hiring for the position. No explanation. No apology. Nothing for wasting my time or the lack of professionalism.
