Phone call with recruiter for initial interest. Then phone call was set up with two engineers. Talked about technologies I wasn't necessarily familiar with. Lots of questions pertaining to Terraform, Linux, and general CS definitions.

Three, four or maybe even five rounds of interviews (do they even know?!!) to get through beginning with a recruiter sifting stage. Can't fault the recruiter, they did their best to sell the job and touch base frequently. But it seems the company themselves don't actually know what they want: There's either a case of "we the business have changed our mind with regards to what we're looking for, so we're not looking to fill this position and don't care whether we do that at such poor timing without regards for what arrangements a candidate has made". Or... They really just wanted a unicorn and don't want to communicate that.

The interviewer hung up on me in the first 5 minutes. We were in a call and and he just hung up. I tried to return the call but clearly he wasn't answering. He responded in email that his phone was not sending or receiving calls but I definitely left a voicemail. Professionally the most disrespectful thing that has happened to me thus far.
