Overall very strange experience. It seemed as if there was a big rush, so I gave a lot of my time with three meetings happening in sequence. First with the CEO, then a staff member, then a third meeting with the two together. The staff member was more polite/professional and asked intelligent questions. The third and final meeting ended somewhat abruptly after 30 mins or so with no mention of any next steps. I followed up via email but was ghosted and received a cold form letter rejection from Indeed. It's quite unprofessional after you've had several interviews and spent almost 3 hours together, in my opinion.
It doesn't take much just to be kind and polite and send a personal note when you're not moving forward with a candidate. That's just pretty standard and is the expected professional approach.
