Initial phone screening, 30 min chat with UX Manager, in person whiteboard design challenge with another designer, final call with the Director of UX and Associate director for more detailed design discussion

It was long and arduous and all I received was an automated email saying they went forward with others. It started with a call with the recruiter, then a portfolio review in front of 5 team leads. Then I received an email saying one of the teams wanted to move forward with the process, so I had 5 back to back interviews. Then, after weeks of hearing nothing, the recruiter entirely ghosting me, I get an email with a meeting invite for another round of interviews. I tried to reach out to ask about what was going on since I still had heard nothing and another round of 6 interviews wasn't in the described process, but again nothing from the recruiter. I prepped for the round of interviews, even though I was unsure if it was even actually happening or if it was a mistake. I completed the round and then 3 weeks go by and I received an automated email. It was grueling. I enjoyed a lot of the conversations, but it was horrible communication in between and felt zero appreciation for the ridiculous amount of effort I put in to this interview loop.
