Phone screening with recruiter followed by three rounds of interviewing, including a panel with a case study that you have to present based on a relevant business problem within the time allocated.

Shockingly bad - I won't usually post negative experiences but this was crazy. Was referred to a position and someone reached out a couple of weeks later for a phone screening. Recruiter showed up 10 minutes late to a 15 minute call without acknowledging, and read me the incorrect job role. After 3 minutes without getting a word in, I told them I had applied to a different role and all the recruiter said was, "they're essentially the same thing." I was then asked standard questions and was told my salary expectations were "very surprising." It has been over a month and I haven't been emailed since, and good riddance to them.
