First a casual behavioral interview/chat, then a case study (you get sent materials to do ahead of time and then go over it in an interview), then several conversations with current members of the company. All online.

They called me out of nowhere while I was at work, and asked if it was a good time to talk. I said no because I needed to get back to work, but proposed a time for two days later, to which he agreed. He sent me an email follow up with the job description, and confirmed the phone interview. When the day came for the actual phone call, no one called. I emailed them asking if we were still on for that day, and no response. I haven't heard from them since. Extremely unprofessional--I would avoid at all cost.
